Hey. Not sure if this is the right forum. Didnt see anything on tech support here. Just looking for a little help here. My GFs rig wont post. When I turn it on, the HD led stays a solid red, and holding the PSU wont turn it off. I have to manually switch the PSU off. I also dont get any beep codes. All the fans turn off, and such, but no post. I tried swapping ram, reseating the CPU and Heatsink. I also tried a different PSU (thinking maybe one of the rails died). But I cant get it to go. I think the mobo died, because wont your computer post without a CPU? Should just beep at ya. I can try a new CPU, from my machine. Which clearly works. I also tried clearing the CMOS, no dice. Any ideas?
 
Your motherboard is likely to beep if either the cpu, graphics card or memory are not plugged in.

unplug everything, everything except the psu, cpu, ram and graphics card.
Make sure the PSU isnt plugged into anything else.
If it still beeps and wont POST it needs further investigation.

The next step would be to reset the CMOS as you have already done.
Quite often a CMOS reset doesnt work so its wise to remove the battery and leave the machine unplugged from the mains overnight.
As its impossible to tell if the CMOS reset has worked, I would do this for a guaranteed reset.

Remove every component and clean the contacts. I advise NOT to clean your CPU pins/socket or inside the AGP/PCI-e slot unless you have spilt something in there. Be very careful if you do!

If the problem still persists, replace the remaining items one by one to find the faulty component.
 
I pulled the battery when I reset the bios. I think its the mobo. I removed power from everthing but the board, and the floppy (its a bitch to get at). And no dice. No beep codes, just sits with a solid HDD activity LED.
 
you havent removed everything thats unnecessary to get it to POST.
If you dont do that you wont know if something plugged in is the problem
 
did you pull all agp/pcie and pci cards from the mobo? it sounds to me like a dead mobo if it wont post with only it plugged in
