Here is a nice overview of your motherboard:

Perhaps reloading the chipset drivers might help:

There is a RAM test here:

Another check would be to try another graphics card (if available).

Keep checking for error messages.

I tried to play Metallica-Nothing Else Metters in Winamp and a new blue screen and error appeared:
NO_MORE_IRP_STACK_LOCATIONS
*** STOP: 0x00000035 (0x83130EC8,0x00000000,0x00000000,0x00000000)
I tried to play the song again and the same thing happened!
BUT,it only happens in Winamp!When i played the song in Windows Media Player the blue screen din't appear.It appeared at the middle of the song
Then i went to Event Viewer and there were these errors which happened at the same time as when i tried to play the songs!!
Here's what it says:
Source:Service Control Manager Event:7001
WHAT NOW???

Double click (or right click) that error in the Event Viewer & post the Description.

Everything is pointing to a or some drivers with the outside possibility of a RAM problem.

I would try the RAM diagnostic from post #11 as well as the chipset drivers.

I'm on dial up so i'l download those ehings when i have much free time(now i don't....)

The Computer Browser Service is a network service. If you are not on a network the error is benign.

When you can I would try the drivers.

Chipset first:

If that doesn't help then try the graphics drivers:

hmm,my brother and i are on a network...but i pluged off the cable...
ok i'l download those things as soon as i can...

Dis-connecting from the network might have triggered that error.
