Hi and thanks for taking time to help. ASUS Striker II NSE 790i GTX 280 1GB OCZ Gold 4GB(2x2gig) DDR3 1600 Intel Core 2 Quad Q9550 Coolmax 1200W WD 1TB 7200RPM XP I finished putting a new PC together last week and I've been having freezing issues with it. First I installed the Windows 7 beta and when I would play games the PC would freeze after 10-30mins and just hang there. I couldn't alt-tab, ctrl-alt-del or do anything to get out of the game but just reboot the PC. I thought it might be a windows 7 thing so I reformatted and installed XP. After getting the XP install finished and the newest gfx driver installed I tried to play a game and it froze up and just hung there again. Getting this PC running as been a hell of one mess up after another. Now I'm almost done and this crap crops up. If anyone can tell me what I need to do to get this working I would greatly appreciate it. Thanks in advance, GFH.
