I had to wait a day for the store to test the board, which wasn't nice, but it's store policy and they've never screwed me before.

The motherboard was dead as I thought, and the CPU checked out fine. Which is what I figured since usually when a CPU goes the motherboard will POST and tell you so.

This is the first ASUS motherboard I've ever had die on me, but it's a relatively low end board so QC probably isn't as high as it could (and should) be. The store replaced it with an identical model, so I'm just going to hope it's not a common defect of these boards.

If anyone wants to know, it's an ASUS H81M-E, an m-ATX motherboard that really shouldn't be used for anything more than what I've got on it. I really can't imagine someone putting even an i5 on this thing, it's budget as hell. It'll take up to 16gb of ram, I've got 8 on it. I'm running an i3-4130, since that's more than enough, and I've also got an old Radeon HD 5770 stuck in it just for light gaming.
