I need some opinions. Last week I tried to "wake up" my PC from sleep mode and it wouldn't come up. It had been on for a few days and was working fine the last time I used it. It never would come back up, so I turned it off and powered back up. I can see that the CD, floppy and harddrive are getting power from the lights on the individual components, but I get absolutely nothing. No start screens, no manufacturer splash, nothing. I also noticed that the system fan isn't turning. The fan on the power supply is working, but not the main fan. Everything else seems to be working from what I can tell. I thought that it might be a mobo problem, so I took all the components out of that case and installed them in another case and on another board. I don't know the condition of this board to begin with since it was given to me and I haven't taken the time to rebuild it yet. At any rate, I pulled the HD cables and power supply from the old PC and put them into the new one, using the exising CD and floppy drive that was in this new case. I get pretty much the same result. All components get power but after the initial power up, everything stops. No signal to the monitor at all. The only difference is that this mobo has a fan mounted directly over the processor and that fan is getting power. Is this a power supply problem or what?
