bluescreening when playing games, attatched minidumps, pls help!!

[mrsafetysays]

every so often while playing either World of Warcraft or Guild Wars, my computer decides to blue screen. i think it may have something to do with my RAM but i honestly have no clue. if anyone could enlighten me as to what i need to fix with my software/hardware, i'd appreciate it.

i've attatched 4 minidumps, if you need more or specific ones, i can provide them.

thanks alot!

Hi,

Suggestion
1. Upgrade ATI display card driver
2. Probably faulty memory. Run memtest to stress test the ram.
3. Run 3D Mark 2005 to test the video card.
