Had a pretty good electrical storm last night so I have a feeling that fried something but I can't seem to find out exactly where the problem is.
Shut down my computer last night as normal and powered off everything using the surge protector power on/off switch. Upon starting up my computer this morning, everything appears to come on (green light on the mobo, fan spins, computer lights up, etc.) but no BIOS screen, nothing. The monitor acts like it's asleep. After a couple seconds everything shuts down like it was powered off (green light on the mobo stays lit though), and then it starts right back up again on its own. Same thing, all the lights are on, the fan is spinning, etc., but still no BIOS or any reaction at all from the monitor. The computer stays on this time though, does not power off again unless I do it.
Now, I've checked the monitor on another computer and it works fine. I tried the monitor in both the graphic card I installed and the one on the mobo with the same results. So I unplugged everything from the computer, opened it up and disconnected everything from the mobo but the power supply and fan (I mean everything else was gone including the RAM). Reset my BIOS by pulling the battery for 10 minutes. Powered it on and the same thing. Starts up, shuts off for a few seconds, then turns on and stays on but no BIOS screen. Now the power supply is connected to the mobo in two slots. One is a 4-pin connector that plugs in close to the fan and the other is a 24-pin connector on the side of the board. If I unplug the 4-pin, it will power up and stay powered up (but still no BIOS). I'm not well schooled in computers so I'm not sure what the 4-pin connection actually does only that something finally changes when I unplug it.
So, with that information, how likely is it my power unit and how likely is it my mobo? Everything appears to be getting power but I'm not sure that means my power unit is ok. I don't have a spare power unit to swap to check it out. Anyone ran into this before? Would appreciate any advice. Thanks.
