It may be a mobo issue, it also could vary well be a cpu issue as well... what do you mean by you put a little bit more grease than you should have?
I knew it was only supposed to be a dot. I'd read it a million times and I'd seen it done a million more, but I just couldn't help myself. I put a light coat over most of the face of the CPU while staying about 2 mm away from the edge. I guess a lot of other noobs pull the trigger a little too hard their first time, too. I'm pulling the mobo out in a little while and taking a look at that. If I get it cleaned up and it looks fine, is there any way to narrow down the problem between either the CPU or mobo? I might be able to get my hands on a multimeter soon, too.
