So I recently bought a new CPU cooler and fitted it without a hitch. Temperatures were a bit high and I thought I'd probably put too much thermal paste on so removed it again. It was drippling over the sides of the CPU so I removed it (carefully) and wiped off as much paste as I could with a sheet of paper and refitted everything. Now when powered up the fans spin for a second, it cuts out, then tries again after a second or two, over and over. No beeps or lights.
I've tried removing every other component leaving just the CPU and motherboard, same result. I checked the pins of the CPU socket and they all look straight. The bottom of the CPU looks a tiny bit blemished, and I think it might be thermal paste. I gave it a gentle rub with meths (alchohol) but it didn't affect it. It did get the paste off the top well though.
I'm using a Gigabyte GA-Z77-DS3H board with an i5 3570k (stock).
