My PC won't fire up....
Discussion
Try replacing the CMOS battery; usually a CR2025 lithium cell.
If no joy at this point then, with the power off, locate the clear cmos jumper, and short/bridge it (usually there is a jumper accross pins 1 and 2, and you need to move it to 2 and 3) for 10 seconds, then move it back. Wait a couple of minutes, cross fingers, power up.
You'll then need to set the system time, and change other settings as necessary.
Should do the trick.

Yep it's either the battery is failing/failed. Or some how the CMOS has tied itself in knots. Grab your manual for the motherboard, look for a CMOS reset jumper in it. Open side panel, remove jumper, drink tea, replace jumper.
Often just pulling the jumper and replacing it is enough but, why waste a good cuppa?
See if that helps, if not, try the battery replacement.
