my friend has that rig,when he runs ut99,CS:s,nba,even mortal kombat 4 ,the BSOD shows up with error message:

that we need to check disk space,he have about 3-4 gig free,and on other partitions has a lot of space,and that we must disable bios shadowing/cacheing,but i didnt find taht option in bios

i install prime95 and runs for an hour and no errors or warnings

interesting is that only ut2k4 runs with no crushing
he reinstall windows a lot of times and the problem is same

so what should i do......
