Well....that's not bad. I had to re-read the thread and realized it's the idle that's freezing you, not high clocks and this started happening after static discharge.
If it's a hardware issue where you've somehow fried your board at least partially I'm not sure what to tell you short of bios reset (which you've already done) or RMA of the mobo (last resort).
If it's a software issue, where something in your windows power settings maybe or something else got borked during the surge, you could try getting your windows install cd/usb and running it on reboot, to get to repair utility and run the repair. You can also do it like this:

if you can't find your windows install cd. If that indicates no issues, you've updated and reset bios, and run all the hardware tests and they're coming up fine, I'd talk to your mobo manufacturer about rma if it's still within warranty.
