UT3 Crash in 64 bit windows

[ZeroWing]

I recently installed a 64bit version of Windows 7 on my HDD. I installed/patched UT3 and booted it up, It plays fine for 10 min then my screen either goes white and i have to wait a couple seconds before I get a picture again or the screen goes black and i have to restart cuz the audio is cutting and I have no response. I installed the latest ATI drivers from the website on my HD4890 and DX10.1 and my game keeps crashing. Anyone else have this issue or know how to fix it? My PC isnt overheating since I checked the temp log when my PC crashed. Thanks~

Only seems to happen in UT3

i have 64 bit vista and it works fine, may be compatibility issue with the game or driver problem?

Have you googled to see if anyone else has the same problem?

This happens to me as well (although in a different game), yes I have 64x Win7. When the screen goes white and returns to normal, it is Win7 changing it's colours back to default, since the game is showing things that different setting can't handle or something. I am not sure if this is just the UT engine that has problems with Win7 or Win7 in general.

If you go into windowed mode (not fullscreen) you will see this happen.
