Hello, My computer restarts by itself and I know it is not the RAM since I tested it (ran my computer with one 512RAM chip and it keeps restarting and then the other). It is getting really annoying since I am not that great with hardware and I've been looking for the solution everywhere for over two months now. I even downloaded motherboard monitor, but I don't know what to do with it :haha: Looks really complex. Anyways, the computer only restarts when I am playing videogames. I would leave it on for 2-3 days downloading things or just idle to see if it auto-restarts but it won't. This point should help to come to a conclusion I guess (for people who understand more than me about computers) Maybe temperature? The only fan I got is the one in the cpu. Sometimes when it restarts by itself it says that "the system has recovered from a serious error" and that it could probably be because of some "wrong hardware installation". Well, that's all I can tell, help will be really appreciated since this problem is getting really annoying like I mentioned . I have speedfan and it registers the following while playing (maybe more): System: 91F CPU: 114F AUX: -54F HD0: 113F HD1: 106F Core: 118F Are these temperatures ok? I am running on a AMD Sempron 3000+, 1G RAM, Geforce 7600GT, 200G HD, Win XP, 350WTS. Thanks for your time.
