Hi, I bought this PC about 1 1/2 year ago and never had any problems with it until recently. I started having blue screen whenever I was playing games (mostly Guildwars and World of Warcraft). I got blue screens only once I played the game for a long time. But now I get the blue screen more and more often, even when I'm just surfing on the web. I can't do anything with it anymore. It boots in Windows and it can stay on for a long time but as soon as I start doing something like surfing the web, burning a cd or playing a game, I get the Machine check exception error. Its always the same error and comes up pretty much randomly, sometimes its at start up, sometimes it takes a while. Pentium D Dual Core 3.2 Ghz Asus P5N32-Sli Deluxe Mobo 1Gb DDR 2 Ram NVidia GeForce 6800GS 560W Thermaltake PSU Windows XP SP2 Home edition I tried all of these things: - All my fans (3 fans + Cpu fan + Video card fan + 2 PSU fans) are working. - Temperature is ok, even tried putting a regular home fan as close as possible to the video card to get lower temperature and still got the error. - Ran Memtest for about 2 hours and rams are ok, even tried different rams and still got the error. - Checked for errors on my HD and found none. - Installed all the latest drivers but it didnt work. Then I reformated my HD. I noticed one bad capacitor on my mobo right next to my CPU. Maybe that might be the problem? I am new with this but I got someone helping me. Do you guys have an idea on what I can do next to fix this damn error!
