Blue Screened.. 3rd time this week.

Hey everyone, I know its been a while, but I have a BIG problem on my hands.
I run a CS:source dedicated server on my home pc, and recently, I've been getting a lot of blue screens. I have no idea whats causing them and no idea what they are about because it shutsdown my PC faster than I can read a few words. It might not even be the server because sometimes when I'm downloading things and listening to music with windows media player it will blue screen. (again, too fast to read it)

I'm in a lot of stress because its happened about 3 times this week!
Please help!

System Specs:
AMD Athlon 64 3500+
2 Gigs PC3200 OCZ Platinum RAM
Chaintech S939 VNF4 Mobo
Sapphire Radeon X1600xt
Soundblaster X-Fi Xtreme Music
7200RPM 80GB HDD
CD/DVD combo drive
With WinXP x64 (Maybe I got an early and buggy version of this?)

I believe I have the latest drivers for all my hardware.

I can provide extra information if needed

THANKS!

I've been getting the same thing as you....in exactly the same programs, although my hardware is different. Do you get the " Blah blah has caused a problem and needs to close" at all? Might be a device fault......or something with your hardware.....any hardware conflicts? If anyone has an input it's appreciated as I'm having these symptoms too.

Upload your dumps here (3-4) should do.
