I booted my PC last week no problems, wen't to open my browser and everything froze. I had to then force shut down with the power button. Ever since then, I've tried to boot the system and no matter what I do it freezes before I get to the log-on screen.
Faulty hard drive (replaced)
Faulty motherboard (replaced)
Faulty RAM (DRAM LED on motherboard) no longer lit up in red
Safe Mode(s) - CLASSPNP file
Startup Repair (Attempting Repairs - have left for over 5hrs before)
Starting Windows animation
All of the above
Booting from Windows 7 disk
Windows Diagnostics tool
Obviously I must have some sort of nasty bug because this has all of a sudden happened. Have searched Google and many forums for answers but no luck. I am rapidly running out of options!
Any help much appreciated.
