I'll start off by telling you my system and what I have tried to fix it. System: Asus M2N-E MotherBoard, AMD 64X2 6000 Processor/AMD HeatSink and Fan, AcePower 450W Power Supply, Navida Geforce 9500 GT Video Card, Dell SATA 160gig Hard Drive x 2, Ocz PC2 6400 2 gig 5-5-5 x 2, and running on Board Internet Port I was using my computer the night before, and now today I try and start it: it started for 5 Seconds than shut off. I tried to start it with the button in the front and it did nt respond, so i flip the switch at the back and when i flip it back on it started right away. But still started for 5 seconds and off again... terrible cycle. I have gone through my computer unplugging different parts and trying to start: Ram, Hard Drives, Video card, Power supply, DVD-Roms. I do not have a diffrent Processor or MotherBoard to see if one of those is the problem. With this being said, I have tried to reset my Bios by pulling out the battery and jumping the jumper to 2-3 instead of 1-2 waited 30sec put everything back to normal..... still shuts down after 5 secs and did not go to anything.... when it turns on for the 5 secs the green light is on. I did notice a little bit of brown on the f_panel in the bottom right coner of the MotherBoard.. is that normal????
