In order to boot, I would have to press power button, followed by reset button within about 2-3 seconds. Mildly annoying, but worked.
Starting about 9 months ago, computer started freezing on BIOS info/POST screen (as displayed below). I have to hold power button until system shuts off, wait about 8 seconds, then power on again. After that, it boots fine.
Checked manufacturer's website for updated BIOS, build on board is most current and only available. Tried flipping jumpers and swapped out CMOS battery.
Although I intended to when I first bought it, CPU nor memory have never been OC'd. System runs stable any other time.
Any ideas for resolution other than new mobo? Thanks in advance.
