Windows 7: Had to force restart during Auto OC process and now PC wont boot

Had to force restart during Auto OC process and now PC wont boot


I have an ASUS M5A99X Mobo which has the TurboV EVO tool that automatically overclocks your system to a stable state. I have had the PC about 4 months and have previously run the tool before with no problems, taking it from 3.6GHz to about 4.2.

I thought I would try running it again just to see what difference it would make as I ran it as soon as I first got the PC so things have changed since. (not hardware changes though, just programs and other settings etc).

During one of its restart cycles the PC hung on trying to start windows (the little windows graphic with the moving bubbles). I left it for over an hour but it still hadn't done anything so I forced a shutdown by holding the power button.

Now my problem is that the pc wont start windows at all now, and gets stuck at the same point and then restarts to the recovery options. Startup repair has run several times and cant fix the problem. I have tried resetting BIOS settings, flashed the CMOS, tried a couple of tutorials on here like resetting the reg files using the regbackup, resetting the boot manager and still the same problems.

Any other suggestions or am I looking at a fresh install? I am fairly certain I haven't done any hardware damage as the Memory test seemed ok, and the harddrive is still accessible. The "BOOT_DEVICE_LED" does stay on initially at startup, but once I get to the recovery options it goes out. I assume this is normal that it goes out, but maybe suggests that there is something wrong with the HDD or the boot settings?

Any help would be appreciated. I am currently copying some files from one HDD to the other (I had an empty slave installed from my last pc) in preparation for having to do a fresh install as I can't find anything other options.

If you have the Windows CD try running the repair from the CD. It is able to fix more than other options.

Your over clock might be causing the problem and maybe heat. Set your bios to default. I have over clocked 3.2 to 4.0 and other that looking good on the charts and grafts I couldn't tell the difference.
Please fill out you specs. It helps others help you.

Busted Memory,
You may also try removing the CMOS battery and waiting a couple of minutes then re-inserting to reset your bios.
