No Beep, No Video Display, and Fan Spins Erratically
This computer showed no video display, no beep, and as observed the cpu fan spins erratically. The problems seem complicated and our instincts tell us. This Compaq Presario SR1000V had not been used for about five months because of this problem.
Troubleshooting this type of computer problem does require a lot of patience specially that you are not hearing any beeps and seeing no display. You might want to suspect problems with the video card, RAM, power supply unit, or the motherboard itself. Proper troubleshooting procedure and technique, troubleshooting safety, and documentation must be observed so that you may be able to solve the problem quick, systematic, and efficient.
The procedure done below is a very good example on how a computer troubleshooting procedure should be done correct. This is a step by step tutorial and guide on how a newbie should when troubleshooting a computer.

Problem : No Beep, No Video Display, and Fans Spins Erratically
Motherboard : Compaq Presario SR1000V, 2.6 GHz 512 MB
Operating System : Windows Media Center
Technicians : Computer Hardware Servicing Class of CLHIDO

INTERVENING FACTORS
- No Motherboard Support CD
OBSERVATIONS
- No Video Display
- No Beep on POST
- CPU fans spins but erratic
TROUBLESHOOTING PROCEDURE
- Before testing the system unit, we must first ask few questions to the owner of the system unit to give us some clues on what and when's regarding the computer problem encountered. Remember that first hand information about the computer problem encountered by the owner or user is the most near-reliable source of idea on what really is the problem of his or her computer. But be warned, I have had said near-reliable because most users being asked lies on the details fearing that the blame is on them. You must ask them in low tone, soft, non-vindictive, and non-agitating manner. The details they give might be useful for your approach in troubleshooting.
- After gathering the information provided by the user, you must verify it by checking and testing the system unit. Be sure to physically check the peripherals first before testing. Try to see if there are missing, blown, or poorly attached cables and peripheral cards. Then after a thorough check, test the system unit and do a detailed observation.
- Upon turning on the system unit, we have noticed that there was an obvious whining sound inside the DVD ROM. There was no video display, no beep or beeps heard, and we can see the fans spinning erratically by when it spins fast then slows down to the extent of almost stopping then turns fast again. This must be a PSU or RAM or motherboard problem. Since there were drives attached, they need to be removed. Once the hard drive, floppy drive, and DVD ROM were removed, the system was powered on and again carefully observed for. The whining sound was gone but there was still no video display or a beep and the fans still spins erratically. The whining sound must have been caused by either of the drives which we verified later.
- Having eliminated the observed whining sound, we must now find out which peripheral or peripherals are failing. On our list we had the PSU, then the RAM, and finally the Motherboard. But among the three, PSU is the nearest candidate to be failing because it main function is to supply power to all the components of the motherboard including the CPU fans. But the RAM is also suspected to be defective so we have to check the easiest component to test which is the RAM. We cleaned the RAM's connector edge with an eraser and powered the system, but it was all the same. The fans still spins erratically. So we transferred the RAM to the next slot and again observed if CPU fans will spin regularly but it didn't. The RAM or the slots must be defective. Since we have an extra RAM, we swapped it with a known good RAM and powered the system unit again. Alas! the fans spins quite regular and we now have a clear display but we can still observe a little erratic spinning.
- Knowing that the RAM was indeed defective and has been tested, our attention switched back to the PSU. It doesn't mean that when as the RAM was initially replaced, it had already solved the problem. Logically, what made the RAM failed is either the motherboard or the PSU. So knowing this, the PSU must be checked.
- Upon checking the PSU, we were not surprised to see three blown capacitors. Though it may be ok to replace the blown capacitors, it is recommended to buy a new one. The system unit that we were troubleshooting had its defective PSU replaced by a new one.
- Two problems found and solved. Now let us go to the whining sound observed earlier. When we plugged in the drives we could hear that the source of the sound is really coming from the DVD ROM and as we tried to open the rack tray, it was stuck. So we manually opened the tray by pinching an eject hole of the DVD ROM and found a CD in it. When we closed the tray back and powered on the system unit, the sound was no longer heard.
- Installation of the operating system was done, appropriate drivers, and the necessary programs were finally installed. The system is now up and running.
SUMMARY
- Troubleshooting problems like this seems so common. The most common problems we have encountered are these the ones we have just worked on. No video display, RAM, and PSU problems are the most common computer problems.
- As we have made the troubleshooting procedure above, problems with display are commonly caused by a failing RAM provided that the video card is ok. Fan problems are generally attributed by a failing PSU or worse a failing of defective motherboard. Also, abnormal sound produced by a system unit may be coming from a CD or DVD ROM, Hard Disk Drive, and or Fans.
No Video, Has Power on a P4VM - MX Motherboard
Troubleshooting Video Problem poses a challenge amongst Computer Technicians. There will be a hard time pointing out or zeroing in of the problem in terms of which peripheral is failing. Most of the time, Video Problems are attributed to a Video Card, RAM, or PSU failure. But in some cases, the RAM, PSU or the Video card hardly be suspected to cause the Video Problem but other devices such as the Hard Disk Drive, burnt capacitors on the motherboard, burnt or grounded card peripherals, and other components least expected to cause the problem.
The question is, how are we going to find and fix the cause of the problem and try to stop it from recurring and what Methods of Troubleshooting are we to follow. Try to see below how we did the fix.

Owner : Mr. Marcial
Unit / Motherboard : P4VM -MX 2.4 Ghz with 512 Mb of RAM
Operating System : Win XP SP 2
Technicians : CLHIDO Computer Hardware Servicing Students
PROBLEM :
No Video but has Power
INTERVENING FACTOR :
No Driver Support CD
OBSERVATION :
When the Computer was turn on, there was no video but has power. The fans of the power supply turns and the indicator led of the motherboard lights. The PSU must less be suspected and we can directly assume that the video system or the RAM must be the failing the component.
TROUBLESHOOTING PROCEDURE :
- Since we found out that there is power from the PSU, the fans are all spinning, and the indicator LED is lighting; checking the power system will be done later after checking all the other peripherals if we can find fault or faults.
- To be able to accomplish such check, we removed all connectors to the drives including the power and data cables and also removed the card peripherals virtually leaving just the RAM, the Processor and the motherboard power connector. There is no video card connected and what we can only check at this moment is the RAM and the Processor.
- Having only the RAM and Processor to check first, we turned on the system unit and observed if there will be a continuous beep that might indicate a RAM problem. But there was no beep. The RAM's are ok and surprisingly there was a live screen and we were able to navigate in the BIOS. The RAM's, Processor, and the Integrated Video System are discarded to suspected of causing the problem.
- The next thing to do is to check the card peripherals. So we turned off the system for safety and then inserted the internal modem. As we turned on the system unit, we pinned it! the video was gone! The modem caused the problem! So again we turned off the computer then removed the internal modem and physically inspected it. We then found out a little burnt area on the largest chip of the modem. The problem was caused by the burnt internal modem!
- We then inserted and connected all peripherals to its proper cabling and header then turned the computer on. It was then O.K. The modem really is the failing component.
SUMMARY
- In troubleshooting video problems, we cannot suppose to suspect the video card, RAM, or PSU to cause the problem all the time. Sometimes, the least suspected modem can cause the problem or other peripherals likely to be expected to fail.
- As we ask the owner of the computer how his system unit failed, he said that the computer did not have video display on the morning after the evening storm. Lightning was everywhere during that night and must have caused the modem to burn in anyhow.
P5PE-VM Motherboard Dead?
A P5PE-VM motherboard was declared dead by the City Computer Technician and when the system unit was handed over to us, it resurrected. As many computer technicians say "If you can't replace the motherboard, replace your technician". This may sound mean but why not consider this thought. As we checked the system unit by powering it up, we noticed that the computer was "dead". There was no video but the fans are all spinning. After some few moments of trying to point out the problem. We got it solved and here's how we done it.

Problem : Computer is dead, No Video but Fans Spin.
Owner : The Dumaguete Public Employment Office (PESO)
Motherboard : P5PE-VM, P4 2.6 Ghz
Operating System : WIN XP PS 2
Technician : Drokz
URL : http://computer-help-tips.blogspot.com
INTERVENING FACTORS :
No motherboard support cd
PC Must be fixed in a day.
OBSERVATIONS :
Upon turning on the computer, we noticed that there was no video but all fans are spinning. so we need to check the RAM's, video card, reseat the processor, and power supply.
Also, the video card fan spins quite abnormally slow.
TROUBLESHOOTING PROCEDURE :
- With this type of trouble are almost always expected to be a video card fault. As observed, all fans are spinning and no video display. So we pulled out the video card and visually checked for blown or leaky capacitors but found nothing different or faulty. So we cleaned the connector edge of the video card with a contact cleaner and inserted it after to its slot. Still upon powering the system unit back, no video, no beep and all fans are still spinning.
- So we switched our suspicion to the RAMs. So we cleaned all the RAMs' connector edges and checked it individually by inserting one RAM after the other on each of the DIMM slots. After doing so, we found no clue to what really caused the problem. We can actually check for the power supply right away but it is best to check the components that are accessible and easier to test. So we decided to finally check the PSU for fault.
- As we open and see the insides of the PSU, we weren't surprised to that some capacitors are leaking. Even if there are capacitors leaking, the PSU may still give enough power to spin up the fans and light the LED's. But the power it produces is not enough to make the system to normally run. So we replaced the PSU and the problem was resolved.
- After replacing the PSU the system runs fine for a few minutes but then restarts. As timed, it was about three minutes before the computer restarts. As observed earlier, the fans of the video card spins slow. So we attached a 12 volt fan to the video card. And upon powering up the system unit, there was no restarting of the computer after three minutes. The over-heating of the video card caused the computer to repeatedly restart.
- Problem Solved!
SUMMARY :
- PSU's can still produce enough electricity to spin up the fans and power the LED but not sufficient enough to power the system unit normally when its capacitors are leaking. So consider checking PSU's if you computer gives you no video yet the fans are spinning.
- An over-heating video card can cause a computer to restart after some few minutes when its components can no longer take the heat.

No Display, Continuous Short Beeps , All Fans Spin, No Keyboard Response on a P4GE-MX Motherboard
Troubleshooting this P4GE-MX motherboard is not as easy as one may think. I have encountered a lot of computer troubleshooting similar to the problem of having no display, continuous short beeps and with all the fans spinning. But as guided with the knowledge of beep code errors, continuous short beeps leads us to say that there is something wrong with the system board. Of course, we can't directly jump into conclusion that the motherboard is defective. I have taken detailed observation and verification before making such conclusion. See the text below how I did the troubleshooting procedure for this computer problem.

Problem : No Display, Continuous Short Beeps , All Fans Spin, No Keyboard Response on a P4GE-MX Motherboard
Owner : City Livelihood and Home Industries Development Office
Motherboard : ASUS P4GE-MX, P4 2.4 Ghz
Operating System : XP / Ubuntu
Technician : Drokz
Website / Blog : http://computer-help-tips.blogspot.com | http://chs-tutorial.blogspot.com
INTERVENING FACTOR :
- No Installation CD
OBSERVATIONS :
- All Fans spin
- No Display
- Continuous Short Beeps
- Keyboard will does not lit
TROUBLESHOOTING PROCEDURE :
*****Please turn off the AVR and unplug the power cord if you'll replace or test any peripheral in your computer system unit*****
- Before the troubleshooting was started, I asked a couple of questions to the students who has used and observed the behavior of the computer before it totally broke. So here are the following observations as said by the students.
Question :
- "What happened before the computer completely shuts down and never give a display again?"
Answers :
- "It keeps on freezing."
- "It won't restart if the restart button is pressed"
Question :
- "Did it only occur once?"
Answer :
- "It did a couple of times as we power it back. But on our fifth or sixth attempt trying to turn off (turning off the AVR) and turn on the system back again, it did not give any display but the fans still spin."
It must be noted that it freezes upon operation and could not be restarted using the restart button. We can speculate that the operating system is least to blame for this trouble. So there are six things to check for this problem. And we need to isolate each of our suspected troubles to screen off mistakes in troubleshooting.
Suspected troubles in the order of priority to check :
- Video Card (improper seating and fan speed)
- RAM
- Power Supply
- Hard Disk Drive
- Operating System
- Motherboard
- Please remember that we will be doing "Isolation Method" of troubleshooting. We will be testing each peripheral one after the other so be careful with power. Always turn off the AVR and unplug the power cord each time you swap a peripheral.
- Since there is an integrated vga port, we can use it instead of the video card. Upon removing and checking the video card for physical defects, we found none. So we proceeded with the checking by using the integrated vga port and turned on the system. But still there was no display but continuous short beeps. We also inserted the removed video card to the other computer system and found out that it just worked fine.
- Video defect has been eliminated. It's time to check the RAM. We simply swapped the existing RAm with a known good RAM from a running system unit. We also used one slot after the other and still got no display but continuously gives out the repeating short beeps again.
- RAM defect suspicion was also eliminated. Since stubborn computer problems like this is attributed by a defective Power Supply Unit (PSU), so the system's PSU MUST be checked. And as it was checked using a multimeter, the power output were ok. Not contented, I opened the PSU to see if there are blown or burnt capacitors on its board but has seen none. So I decided to swap it with a known good PSU then powered on the system. Again, there was no display but a continuous short beep.
- Suspicion on the PSU was again eliminated. So I switch my attention (a little attention) to the Hard Disk Drive and the Operating System. To check two things that are relative in one time. I decided to remove the Hard Drive immediately from the system unit then powered on the system unit. Again, there was no display but a constant repeating short beeps. It seems the solution will go no further. I have suspected the bios to have crashed. All of its peripheral just works fine. I even swapped the processor but still has no difference or changes.
- So I search for the documentation for Pheonix BIOS and found tons of documentation about the matter. The dreaded constant repeating short beep was an indication of a failed BIOS and the only way to fix it is to hot-swap. There was no way to flash it because there was no display and hot-swapping was the only solution. I cannot afford to hot-swap it with the other working system unit because it might end out having two computers broken and the training center had only 4 working computers. Too bad I can't perform such hot-swapping for the computer. But anyway, the computer didn't go to waste, it is now used by students to practice assembly and disassembly of the system unit.
- Problem not solved or was limited to solving it
SUMMARY
- It is good to note and check the beep errors given by a failing system unit. Just like a repeating short beep that indicates a BIOS problem. The troubleshooting should have not taken long enough to spot the cause of the problem. It is also noteworthy to check documentations on the CMOS manufacturer to confirm or verify your suspicions.

Reported Defect: No video no beep codes sounds dead system unit
Computer Name / Owner : Bobo Pague
Date fixed: August 23, 2009
Place: Barangay Taclobo, Dumaguete City
Unit: ATX
Computer Description:
Motherboard: ASUS
Processor: Intel ® Celeron ® 1.80 Ghz
RAM: 1 Gb
Operating System: Win XP SP2
Checked By: Andrew Dahilan - 09058538259
Interview Report:
The owner said just one day it turned off and then really gone dead. The system was sent to two respected Computer Servicing Shops in Dumaguete and both shops said the motherboard is defective or dead.
Observations:
>No Display
>No Beep code
>PSU and CPU Fans Spinning
>Numlock don’t lit on startup
Troubleshooting Proper:
>Since the system was already passed down to me, I assumed its peripherals had been checked thoroughly. So I removed all the peripherals and tested each to verify “their” findings.
>First, I removed ALL removable components and turned on the system then observed the total functioning.
>Then, after which, the CMOS Battery was inserted and turned the system on. Still observing, the result was the same as the first approach.
>The CPU was then placed back in its socket and retested by turning it on. No beep codes, and display.
>The RAM was then tested next, yet still ..no life.
> Power supply was then suspected to cause the problem. PSU was then removed and opened to see if there are blown components (look for blown capacitors) but we found the PSU in good condition.
>Going back to see if it’s a RAM related problem, we inserted a known good RAM. But then again, still no display and beep codes. Changing the slot placement of the RAM and tested each attempt, still there was no sign of “life”.
>It could be the processor that is dead or perhaps really the BIOS or RAM. Confusion begins to pile up. So I rechecked each major component back again and to which I should be starting with the Motherboard.
>Reviving the Motherboard back to life (if is it dead or it could be) is an impossible task. A cell phone techie told me that you really can’t fix its board, but instead it is just to be “heated-up” using some hot air equipment. So I guess it should work the same as the motherboard (technically they are both computers). Instead of using the hot-air equipment used by the cell phone technicians, we borrowed and used Carla’s hair blower (the beautician downstairs of our center). We then removed the components from the motherboard and the motherboard itself from the system casing and checked the motherboard for cracks or other visible and possible defects. Then the heating and blowing process continued using Carla’s equipment. After heating the motherboard and its components, we re-installed the board and its components back to the system case for testing.
>Inserting back the CPU, CMOS battery, and RAM to the board, ALAS! There was a display on POST! But it just lasted for about 4 seconds and the system shuts down. At least there was a sign of life. ?
>Still confused, re-checking the major the components back for the third time and the attempt seemed to be doomed for failure. The motherboard is the last to blame for this stubbornness of the problem. But in the contrary, why were it able to show us the POST? Think. ?
>BIOS loads its information to the memory during POST right? Let’s check the memory.
>I have reseated the RAM to the other slots but it seems the only functioning slot was the first slot we tested where the POST was temporary seen. So I cleaned the slot by running a thin flat screw driver unto its slot and brushed it up (use a contact cleaner, the method used here is barbaric!). After which, the system was up and running and was able to enter the BIOS setup!
>I tested the HDD if it is running but unfortunately the BIOS cannot detect it. We used another good HDD and that’s it!
>Win XP Sp2 was then installed on that hard disk and some utilities and applications.
>The system was brought to its good state after being observed for 1 week (it is still kicking to this day as I write this report). Well I told the system unit’s owner for what problems were found and what peripherals to buy…and guess what, the system was given to me. I now own the system. ?
Trouble(s) found / Defective components
>RAM is found defective
>DIMM slots were flaky and tarnished
>HDD is found defective
>Motherboard was possibly defective
Remedy:
>Heated-up the motherboard (Motherboard is suspected to cause the problem)
>Cleaned the DIMM slots and replace the RAM
>Replaced the Hard Disk and installed and Operating System and other applications and utilities.
Summary:
Check all major components first (RAM, Video Adapter [if present], CMOS Battery, CPU, Jumper Settings [use manual], and then the Motherboard. Use isolation method for troubleshooting. The possible defects of the fixed system were: poorly seated CPU, tarnished or non-conducting connector edges possibly because of humidity (DIMM slots), defective motherboard component(s), and incorrect BIOS settings.
