Hi guys!

I recently bought a new pc and installed windows xp pro and the drivers myself.
I'm starting to think that was a bad idea

The blue screens appear mostly when i'm running a few applications at the same time.
For instance, when i'm listening to some music in winamp, firefox is open en downloading something en i'm loading a game...bam! blue screen.
It happens alot when i'm transferring files and/or downloading something (which is a file transfer too i guess )

The blue screens appear to give different info every time it occurs.

In the log 'help and supprt in windows) i get this: "Foutcode; 000000c2, parameter1: 00000007, parameter2: 00000cd4, parameter3: 00000000, parameter4: e537f3a0. "

I entered the '000000c2' value in google and found your forum. If what i read here is correct the problem is: "Its a double free, which means that usually, one driver allocated some memory, was done using it, and freed it, then someone else (or the same driver) tried to free it again."

I used the 'debugwiz' somebody here recommended (http://www.d-a-l.com/help/attachment...tachmentid=127) and this is the log i got back:
