I ran Windows Update on my Windows 7 64-bit machine recently, and elected to reboot after the updates completed. My machine failed to completely power off after starting the reboot and I had to hold the power button to completely power off. When powering back on now, the machine won't POST.
After pushing the Clear CMOS button on the back of my Asrock Z77-ITX motherboard, I was able to get to BIOS, but the machine failed to POST after exiting.
Now I cannot get back to BIOS, even after pushing the Clear CMOS button. Did I fudge my machine after the hard power-off when trying to reboot?
