Ok guys first I like to say this is my first post. I have been browsing these forums for a long time the information has been great. Anyway so here is my problem. I have a Dell Dimension 8400 I have had this computer for over four years never had a problem with it. I play World of Warcraft on this computer since day one never ever had a problem before. One day when I'm playing I start smelling this weird burning smell like plastic it keeps getting worse. I open the box look for anything burning or melting don't see anything. The smell is the strongest by the powersupply and the p4chip / heatsink. So I figure to myself must be the powersupply. Run to the store upgrade to a 500 watt standard powersupply hook it up and the same incident happens again. That burning smell and the computer locks up. I open up the box look around the fans are all working but I noticed that the video card and near that area is really hot. Any idea's where I should go from here. Should I junk this thing I don't want this computer to burn my house down. Thanks for any help you guys can give me.
