Here are my specs. Mobo: ECS G31T-M7 CPU: Intel Celeron Dual Core E3300 Memory: Elixir DDR2-800 1GB I've already tested my PSU by shorting the green and black wires, they're perfect. The power switches, I don't know but I'm pretty positive that they're okay. No beeps occur, since my case doesn't have any speaker. I've also tested the cases' indicator lights, they're good too. And then I also made sure I got the connectors on the front panel connected correctly. The CPU fan doesn't work, no lights, no anything. It's been quite okay this morning but I have to attend to something so I shut it down and when I returned to turn it on, it just won't. I think it's my mobo, the chip that has the manufacturer's name on it heated up like crazy and then it won't turn on. Still, I don't know what happened, because the specs are all new. I also tried resetting the CMOS but nothing happened. Help!!!
