System won't post

On my main PC I rebooted and pressed delete to get into my bios and once in, it froze. The last time it did this my overclock was too high and I had to jump the CMOS. But in this instance I had a stable overclock for about a week. I rebooted again and still froze in bios. So I decided to jump the cmos to fix everything. It didn't work...the first time jumping the cmos didn't work for me so I'm kind of shocked/scared.

I have no clue what is going on and why it won't post but I need to get back on it ASAP because of some important things I need to get to.

try the following:
  • hold the front panel power switch depressed until shut down;
  • switch off the power supply - or, if no switch, unplug it;
  • depress the front panel power switch for twenty seconds more;
  • jumper, or (carefully) short the RST_CMOS pins momentarily;
  • unplug all USB devices, except keyboard and rodent;
  • PSU switch back on;
  • power up - first thing, enter the BIOS and do the "Load Optimized";
  • <F10> to save and exit;
    hopefully - good to go!
