So, as far as I know, my computer's been out of power since the Monday before last. I got a new PSU today, I plugged it all in, and pressed the power button. Nothing happens. A light on the mobo is lit, which means power IS running through. I've already ruled out a couple of things. 1. PSU, it's new, so i would suspect that it isn't bad. 2. Connections, I triple-checked the connections, and I even switched the power cables on the DVD burner and HDD's. 3. I checked the power button connections, and even went as far as pulling the face plate OFF and pressing the button. Also, my computer is really dirty, and 5+ years old. Specs: E-Machines T3830 Intel Celeron D, 2.4 GHz 1Gb of RAM 2 HDD's, 80Gb + 100Gb Creative Sound Blaster Audigy EVGA e-Geforce 8400 GS 512Mb Gfx card BFG 450w ATX12V 2.2 PSU I've done everything I could possibly think of. I'm currently on my Wii writing this post. And I'm sick and tired of it.
