I tried to replace my stock fx6300 cooler with a coolermaster hyper 212 evo (which was a pain in the ass in itself) and since then my pc won't turn on. I've tried reconnecting the on/off connector from the case on the mobo and tried reinstalling the stock cooler. I guess that more or less rules out the 212 being faulty and so I'm thinking that I may have damaged my motherboard during the un/in/reinstallation process... How would I go about testing it to find out? Or should I just bite the bullet and buy a new mobo, and OS? :/
