I'm using Windows 7 Ultimate. My C drive is a 500GB WD Caviar Blue and my motherboard is an ASUS P5N-E SLI.
Last night my computer restarted unexpectedly and after that it kept going to BSOD, restarting of freezing, usually before Windows had finished loading.
I've tried running checkdisk 5 or 6 times, but every time it's frozen restarted or gone to BSOD before completing.
I've tried loading my Windows 7 system repair disc several times but my computer's always frozen or restarted before completing any repair.
I've tried inserting a new Seagate hard drive and restoring from my back up on an external drive using Acronis TrueImage Home 2010 three times, but the computer was unable to detect my external hard drive despite trying several USB ports and the screen always froze at some point anyway.
Also, for the last couple of months or so, when I've turned my computer on in the morning, the time has been wrong, usually giving a time from between 11pm and 12am the previous evening which may or may not be a clue to what's going on.
Please can someone suggest what I can do to get the computer working again?
