Here's what what makes me think it's a bad motherboard: When I start the computer the processor fan starts, as does the case fan, power supply fan and the bios fan. The DVD drive starts, but only does the initial reading. There is no output to the monitor. The hard drive doesn't respond. The keyboard lights never turn on. And worst of all, the internal speaker never beeps.
I've tried disconnecting everything that isn't important (like the DVD drive, HDD, un-needed PCI cards), still no luck. Also tried throwing in a Linux Live-CD to see if the DVD drive will start reading the disk, but that was a no-go. It did the initial read again, and stayed silent. I've made sure the nuts that the motherboard screws into is in the right places. I'm sure I've tried some other things, but can't recall off hand right now.
Any one have any suggestions, or can confirm that this is indeed a bad motherboard? Replies appreciated.
