Hi everyone, Here my problem, When I boot up computer windows starts and works for a while then I get blue screen saying a process or thread crucial to system has unexpectly exited or been terminated. Computer restarts but now bios can't find my hard drive. Primary SATA not found. If I turn off main power for a couple of seconds and start back up it finds the sata and boots windows until it happens again. I figure it has to be something with the board or bios. I have a P4 3.0, 1gb kingston ram, 160gb seagate sata hd, Msi mainboard. Any help at all would be great. Thanks alot.
