Hello. My PC shows me BSOD when I try to play 3D games and during 3gp and flv video playback. It also turns off and the system speaker starts beeping when I try to reformat.

I have read threads of other people having similar problems but I understand that the problem can be caused for various reasons. This are the specifications of my PC:

Operating system: Windows XP Pro SP2
CPU: Athlon XP 3200
Ram: 2x512
Sound Card: Realtec
Graphics Card: nVidia 7600 GS

Can someone please help?

I have followed the instructions on the "BSOD Diagnostics" thread and I got the following analysis from Microsoft's Debugger:


IRQL_NOT_LESS_OR_EQUAL (a)
An attempt was made to access a pageable (or completely invalid) address at an
interrupt request level (IRQL) that is too high. This is usually
caused by drivers using improper addresses.
If a kernel debugger is available get the stack backtrace.
Arguments:
Arg1: b9d0dffc, memory referenced
Arg2: 000000ff, IRQL
Arg3: 00000000, bitfield :
bit 0 : value 0 = read operation, 1 = write operation
bit 3 : value 0 = not an execute operation, 1 = execute operation (only on chips which support this level of status)
Arg4: 804db973, address which referenced memory

First off try running MemTest.

This runs off a boot floppy or CD.

If this were a RAM issue your RAM would most likely show immediately as Failed.

Although listed as a driver error your "reformat" remarks indicate possible hardware failure.

It is not my RAM since I have removed either stick and the problem persisted. And it's not my graphics card either since i have changed it recently. Is there any way to find out which (if any) of the hardware is faulty? Maybe from the sound pattern from the system speaker?

IRQL_NOT_LESS_OR_EQUAL error is often caused by overheating. How are your computer temps?

I have just cleaned my CPU fan and cooling system which were full of dust and I get temperatures around 45-50 C but the problem persists..

I get temperatures around 45-50 C

Is it while idle, or when playing games?

That's the temperature reading in the BIOS when the PC crashes and restarts..

Get RightMark CPU Clock Utility: http://www.softpedia.com/get/System/...-Utility.shtml to monitor your temps in real time.

It says N/A where it should say the CPU's temperature. This is what happened with other software I installed. Are there any settings to fix this?

What other program did you try?
