I have a 775Twins-HDTV mobo with 1gb ram, p4 d dual core 3ghz cpu, one dvdrw, one 200gb sata hdd, one fdd, one 400w psu, one silverstone tj08 case. I was experiencing random shut downs and stop errors when running windows xp pro so i decided to try a fresh install, i formatted then started the install. The text based pasrt of setup completed successfully but after rebooting to start the gui part of setup it shut down again. Ive tried setup with the standard hal (pressing f7 at beginning of install) but no difference. Ive tried unplugging the two case fans from the psu and any other devices i could power off but this also hasnt made a difference. Im fairly sure this is a hardware issue but im led to believe it could also be a bios problem. Im using version 1.4 of the bios and the latest version is 2.10. Can anyone shed any light as to what could be causing this?

Thanks in advance
