Does the fan on your CPU spin when you power it on?

Mercury PI865D7 Motherboard system is won't turn on. I Checked SMPS and RAM. it's also a good then what's the problem for this....And Coming high pitched Bee Sound Repeatedly.....

Hello the manual can be downloaded here:

Check the ram modules, and the graphic card.

How many beeps comes, when you start the pc ??

Here is a list of beep codes:

One long beep is a ram module failing.
Try insert one module, and reboot.
The problem could also be, the power supply.

Here is a fault finder guide:

Best of luck

Hi I am working on a abit A 17 mother board it was taken apart by my nephew. I think I have every thing back togather, but when I turn it on it beeps and shows code 92,well I think thats what the l e d box...

Hi, you can download a manual here: 478&pPRODINFO=Manual

The fault could be the cpu, wrong type of ram, a faulty ram module
or a fault in the mainboard.
Check all the settings in the manual and the bios aswell.

Here is a list of beep codes:
Basic Beep Codes for ABIT AWARD BIOS Motherboards

  1. No beep at all - this means your motherboard is dead, either due to a defective or underpowered power supply, poorly seated CPU or RAM, or a dead-on-arrival board
  2. One beep - board is working fine
  3. One long beep then machine shuts down - faulty, improperly installed or missing CPU
  4. 1 short(Beep) System booting is normally
  5. 2 short(Beep) CMOS setting error
  6. 1 long - 1 short(Beep) DRAM ERROR
  7. 1 long - 2 short(Beep) Display card or monitor connected error
  8. 1 long - 3 short(Beep) Keyboard Error
  9. 1 long - 9 short(Beep) ROM Error
  10. Long(Beep) continuous DRAM isn't inserted correctly
  11. Short(Beep) continuous POWER supply has a problem
  12. A two-tone siren, generally caused by overheating or out of specification voltages
  13. Four beeps then machine shuts down. This is because this version of the BIOS will shut down your machine if no fan tachometer signal is detected on the fan header. Make sure you attach a fan to the FAN1 or FAN4 header or clear CMOS to reset to default (no checking).

My compaq persario sr1000 power is on the fan is on. but it beeps with a short beep and keep on. beeps pause and beeps again all with the power on but no picture on the moniter

Your ram/ram slot may have gone bad, contact Compaq Tech support for detailed instructions.

For a basic idea of what to do if you know what your doing:
1. Pull out 1 ram card in the first slot
2. Start up system
3. If beeping appears leave that slot empty
4. continue until beeping stops

Side Note:
If you keep removing all the ram cards and the beeping continues, I probably got the wrong error.

Sir i have dell GX280 system 3.0 GHz optiplex. 1gb ddr2 ram with 80gb sata hard drive. Sir, my problem is this first i brought a system it runs fine but sometimes a day it hangs up. i return this...

Plz check your memory with memtest. It can be downloaded from .
Unzip the downloaded file and burn the ISO file to a CD and boot your system from the CD. It will check the memory of your system and it will indicate any error replace the memory.
Also check your memory slot is clean .. you can clean your system memory slot using a anti-static brush (you can use a tooth brush if anti-static is not available) and IPA

Tried to start computer it won't boot and keeps beeping

It's telling you something is wrong. The BIOS (Basic Input/Output System) is detecting something is already wrong. Usually, this could be the RAM is bad, there's no Keyboard or Display connected, or *********** board has gone bad.

Check the easiest thing first (connectors to peripherals). Then check the RAM to make sure it's not gone bad.

It's hard to say w/o doing a lot of testing on which component is causing the problem.

Motherboard was working fine, but now after some time PC starts up without display, only spinning drives but no beeps telling problem. Removed graphic card but still no beeps!! Whats wrong?..

could be faulty PSU,memory or mainboard itself is gone.
pull all parts except psu,1 stick of ram,1 HDD. If it boots, start adding parts one at a time until it doesnt boot..thats your trouble maker. IF it doesn't boot stripped down then it is like I said at first.

Gigabyte GA-945P-S3 short beep codes on cold boot. Tried reseating RAM, didn't help. system runs fine after beeping stops

Using the manual for the Gigabyte GA-945P-S3 MB. Go to page 71 & you'll see bios beep codes for your board: AWARD BIOS Beep Codes 1 short: System boots successfully 2 short: CMOS setting error 1 long 1 short: DRAM or M/B error 1 long 2 short: Monitor or display card error 1 long 3 short: Keyboard error 1 long 9 short: BIOS ROM error Continuous long beeps: DRAM error Continuous short beeps: Power error As you can see there isn't a code for three short beeps. When you boot your system try to pause your boot up screen. See if the bios is reporting the correct total of memory in your system. Bios codes from the link below. 3 beeps for the AMI bios code reports Base 64K RAM failure. You can test your memory. Go to Scroll down the site to just under the three screen shots. Download Memtest86+ V2.11 You have a choice in making a bootable floppy disk or a bootable CD-ROM disk. Once completed you boot your system to the testing program. Memtest will check your system memory. This should help. Thanks for using FixYa! Mike

My HP dv5000 laptop has AMI BIOS beep code - 4 beeps

It sounds like either RAM or VIDEO problem to me. (I can't remember the specific beep sequence for AMI bios errors).

Hard to diagnose in Laptops.... if it was a desktop you can just start swapping out the RAM DIMMS..... are you techo enough to check whether you have 1 or 2 RAM cards installed? If 2 then run it with each card in turn to see if it boots (indicating 1 faulty RAM stick). If only 1 then try running MEMTEST on it to see if any errors. (I like HIRENS if you have it... I think it usually has latest MEMTEST on it).

If your cards all pass then its very likely a video problem. If its onboard video with no expansion slot (likely in a laptop) then you may be buggered.

Let me know if you need a hand doing any of the above.

Intel Original Motherboard 946 with duel core processor.

As you said the system is restarting because of power section problem.
Try to change SMPS and see the difference. Even though if it fail.
Try using single ram if problem repeat change with other ram.
Load bios defaults.

If Not Ok

Contact Intel Support:

With your bill No, Serial No & model no.

or you can mail to:

Hope this will work...
