When I run games (The Battle for Middle Earth, World of Warcraft) I see a split second of video (The EA games loading screen for BFME and some info on WoW) and then the screen either crashes to complete black (with sound running in the background, and i can press ESC to go back to desktop where the graphics are fine) or distorts to lots of bizarre colours (Much like when you'd put noclipping on on an old game of Quake and wander too far through a wall)
It's a nVIDIA Geforce4 MX 4000 128mb ram
The processor is a P4 3.2mhz
512mb RAM
Please help, i'm tearing my hair out :!:
