hey leonardsix,
I believe Doby's earlier post is on point. In my experience with AMD processors, in particular an older T-Bird 1.4GHz, one of the rubber bumpers on the processor seemed to dry out over time causing the CPU fan to not sit squarely and with even pressure on the CPU itself and it took about 5 seconds for the CPU to burn out after powering the machine on. And let me tell you, it was visibly black and burnt. My machine behaved the same as yours, all fans etc powered up and the light on the mobo itself was on but my monitor screen was black/blank. Also, even if your machine is not powered on but you have the power cable connected to the power supply etc the light on the mobo will be on until you take power away from the box. I replaced the CPU and the machine was back in action. The mobo - memory - all PCI cards etc were fine. I highly recomend using silver oxide thermal paste when you reinstall the processor and fan. You may even notice slightly lower temperature readings using this paste versus using generic grease.
Best of luck to you!
