Question about Compaq (388746-001) ( 388746-001) Motherboard
The computer originally would not power up. So I purchased the correct power supply and installed it. Now the symptoms are: Plug power cord in power supply and the power comes on immediately with out pushing power button. Only the CPU fan comes on and the power light is red (bad) not Green (good). You can hear the harddrive spin up but nothing else happens. No video. No POST beeps. Nothing. If you push the power button nothing happens. When you Push and hold the power button for more than 4 seconds the Harddrive LED lights solid and the CD drive lights green solid along with power light stays Red and CPU fan stays on. After this if you push the power button the Hardrive and CD LED's go out Power light stays Red and CPU fan stays on. Power can not be turned off except by unplugging Power cord. Anyone see this before. Fried motherboard or CPU?
Either the new power supply you purchased is not functioning correctly. But, assuming it is now that you are getting some form of power to your PC, it is very likely the motherboard. Whatever fried your old power supply (or it could have just been the power supply itself) most likely fried your motherboard in the process. Probably not the CPU since the MB can't even post.
