Windows won't boot after overclock!

post #1 of 8
Thread Starter 
I successfully overclocked my CPU, restarted PC now it gets past the bios screen, shows 'starting windows' screen for about 2 seconds, flashes blue screen then restarts everytime.

Any ideas how to fix this? Could it be OS corruption?

I've set bios back to default settings with no change to boot up.

Thanks

Ouch... I had this issue before. Turned out to be a driver issue. Can you get into Safe Mode? Also, try doing a start-up repair. They are relativity painless....

If Safe Mode does not work, what is the last file before it hangs. I might be able to help you out.

Startup repair didn't work.

I can't get into safe mode at all. Last file loaded before crashing to blue screen says CLASSPNP.sys



Blue screen reads: a problem has been detected...
If this is the first time you've seen this...
Check for viruses on your computer...

Man, I feel like a total idiot now! I thought I'd checked the HDD settings but checked again and it said 'AHCI Disabled' - changed it back to IDE and now I'm logged in.

Whenever I've had this problem before, it's said something along the lines of 'cannot find boot device' or something. Never crashed to blue screen.
