Well I have the above board and an Athlon XP 3000+ (Barton). Running at 400 FSB with a pair of Geil 512 MB PC3200 DDR in dual channel mode. Using onboard audio and a GeForce FX 5600 Ultra. Power supply is a Mustang 350W. OS is Windows XP Pro SP1. I have some problems: - Usually any game I play will crash anywhere from 10 minutes to a few hours. Not just 3D games, I have 2D-only games and they crash too. By crash I mean the system either hard-locks or reboots itself, not merely a crash to Windows desktop. - Another thing that will guarantee me a crash is trying to encode video files in VirtualDub. - Another problem is I cannot burn CDs at more than 24x though I have a 52x burner that worked perfectly in another computer. If I try to burn faster I get a buffer underrun within the first minute. Also I notice CPU usage is near 100% when burning a CD. I have run SiSoft Sandra tests and cannot find any problems with the HD transfer rates or memory bandwidth, I can't think of anything else that would cause the buffer to empty. I notice when I boot up after the crash that my CPU temp in BIOS is around 61-67 Celsius. Seems fine to me since AMD says the max die temperature for this CPU is 85 Celsius. Anyone have any ideas?
