Windows 7: No Aero theme - Widows Experience Index Not computed

So I just overclocked my processor a few points, and upon booting up my computer, the Aero theme was 'busted.' I tried running the troubleshoot, which claimed I had no issues.

I opened up the Windows Color option, and was greeted with only a Windows 94 looking theme option. (images below) Everywhere I look has no information on this issue.



I fail to see how overclocking my processor only a little bit would cause this issue. All of my drivers are up to date, my computer can easily handle the small amount of overclocking I did, and windows is up to date.
I tried going to Performance and Information and Tools and using 'Re-run the assessment,' and I get 'The Windows Experience Index for your system could not be computed.'

I run with a NIVIDIA GeForce GTX 550 Ti and a 990FXA-UD3 motherboard with an AMD FX-4100 Quad-Core Processor now overcloacked to 4.2 GHz with dual monitors.

I have 12 GB of DDR3 RAM and my OS is Windows 7 Home Premium 64bit.

Please help.

I assume you clicked on the previous theme you built and still no changes ?

There is no reson to OC that cpu.

I did, yeah. I looked at all the themes and the color options for the themes and there were no changes.

If you didn`t get your video drivers from nvidia.com, I would download them from there and do a custom/clean install of your vid drivers, then restart the pc and try again.

This should be them, but double check.

Why wouldn't you get the official drivers from the site? Thats just silly.

Anyways I reinstalled the drivers and everything seems to be fixed now. Dont know why, but all I care about is the fact its working.

Well alot of people don`t know to do that, excuse me for trying to help. Have a Good Day

Imagine that, my suggestion worked.

How did you OC - change the multiplier only, raise the voltage ??

Try only to change the multiplier - e.g. from stock 18 to 23 and see what happens. That should get it to appr. 4.6GHz.

I raised the voltage and changed the multiplier. I'm not bringing it up to 4.6 GHz.

Turned on my computer today and the same issue is back. I really don't want to have to reinstall my graphics drivers again.

My suggestion was to only change the multiplier, not the voltage. Can you try that.
