I was running my Serial ata HD (wd raptor) in compatiblity mode (re-routes the serial ata to the ide bus) and I decided I wanted to run directly on the serial bus. I switched the setting in the bios and the after post the windows starts to boot (with the green meter at the bottom) and all of the sudden, for a split second, a blue screen with words appear and the computer restarts (its to fast to read). I tried in safe mode with the same results. Does anyone have any ideas? Thanks in advance.
