Alright ive got a friend who's got this problem. He starts ja on any server then after about 10 mins his computer just shuts down. Ive goten him to reinstall, have only the nessessary stuff in base folder ''no downloaded skins or maps and crap''. His harddrive is not full gots plently of space. I'm thinking its his vid card but idk. Any ideas would be a great help.
It just powers off suddenly with no warning? If that's the case, it sounds like the video card overheating. If that's the case, check the video card fan.
