I got a wild one! biostar geforce 6100-m9 socket 939 amd athlon 64 proc32 spd = 2010mhz win xp pro latest bios and drivers provided by biostar loaded in. I thought I had a windows problem but i took a clean drive and reloaded xp onto this pc. I have monitored the chip power it appears to be ok. Stress tested the chip with the biostar software and it passes. Just at a loss when it comes to debuggin. I have gotten 1 blue screen. Driver.irql.not.less.or equal atapi.sys.address.ba712bb8 base at ba70b000 date stamp 41107b4d This pc can run for 2 hours or 2 minutes before it reboots itself or shuts off. Right now its rebooting itself more than shutting down. Any suggestions?
