Been fighting this for a couple of weeks. Initially I thought it was caused by my new graphics card, or maybe my OS, but I've now changed both and the problem persists.

On my ASUS M2N-SLI deluxe mainboard for the past couple of years I was successfully overclocking my AMD Athlon 64 X2 5000+ Black Edition CPU to about 3.2 GHz. I noticed a couple of weeks ago it was running at stock 2.5 Ghz so I went into BIOS and everything was still set to manual overclocking, multiplier was at 15.5 and bus speed at 206.

After several reboots (and trying to find a downloadable copy of ASUS's AI Booster on their site, which seems to have vanished, so I could try to overclock at the GUI level) and trying to swap the multiplier and bus speed (multiplier at 12.5 and bus speed at 256) I still get the following once I get to the desktop.

Originally was running WinXP SP3 32-bit
now running Win7 Enterprise N 64-bit

Originally running EVGA Geforce 8800GT 512MB PCI-E
now running ATI Radeon 5770 1GB PCI-E. Getting this weird behavior before and after both changes.

Not an emergency but a major annoyance. Please help!
 
Trying both ideas. Here's the new info. Still getting the error.

Here's the new BIOS info:

CPU-Z version 1.53.1 (seems to be the oldest version I can find on their web site):

And to attempt to validate the info in CPU-Z here's the Win7 screen:

If you turn off cool and quite it will report correctly in windows 7, silly bug but easy to fix bios option
