So this is my first time building a system. I was installing a cooler for my cpu last night (amd athlon 64 2800+) and everything was going fine. I installed it and then tested it. I pushed the power button and it ran for about thirty seconds and then it shut off unexpectedly, I did the test again and it did the same thing. Turns out I installed the cooler wrong. So I reinstalled it and it works fine now. What I want to know, in those couple of times I tested it out could I have damaged my cpu by letting it overheat like that? It's still booting up so I think it might be fine. Is there some way I can check to see if it's damaged?
