I'm building a new computer with an amd64 x2 4600. When I installed the RAM I didn't press it down all the way. So when I tryed to start it I heard the dvd drive click on but then nothing. After messing with it for a couple minutes(not noticing the ram) I went downstairs to consult the internet. When I came back up twenty minutes later and starting looking at it again I noticed that my cpu and heatsink were extremely hot(like burning hot). Finally I notice the ram fix it try to start the computer but my monitor says "no signal" So I guess the question is, can a cpu running for 20 minutes with no heatsink fry? Or is it just the ancient video card I'm trying to put in it?
