Today, I decided to clean out my older computer. After taking the components out and cleaning out the case, I put them back in as they were before (that I know of). The problem that I am having is that my computer refuses to boot. The light goes on for about 1/2 a second, as do the fans spin, but then it dies out. This is with the CPU 4-pin connector plugged into the motherboard as well as the standard ATX connector. All components are in working order as they were working before (they were just very dusty, almost 3/8 in of dust everywhere!), but the PC just refuses to boot. Without the 4 pin CPU connector plugged in, everything powers on properly, but nothing is displayed on the screen.
Motherboard: M2N-MX-SE PLUS
RAM: 2GB DDR2 RAM
HD: One 20GB IDE HD, One 500GB SATA HD
CD/DVD: One IDE DVD-RW drive.
CPU: AMD Phenom (don't know exact model, but it's 1.8GHz Quad Core)
POWER SUPPLY: 350W, No PCI-E connectors, one SATA, a few Molex... etc.
Any suggestions would be greatly appreciated! I don't know what went wrong!
Also, I know that there are also PCI-E connectors that are 4pin, but this is the only 4pin that I am aware of on this computer. There aren't any other 4pin square connectors on the 350W power supply.
EDIT: Mods, can you please move this into the "Internal Hardware" forum? I thought I selected a new topic there, but I didn't. Sorry!
