Okay. I have just run the scandisk on the drive and told it to search for and fix any bad sectors. Scan disk went thru 5 stages and said it was finished.
It did not report any errors, but i dont know if it does that or not, anyway, I then rebooted and it booted windows ok, and without running disk check at start up.
I hope this takes care of the problem, and I also hope this is not part of this mobo's problem, with data corruption?
