I have a computer that will not bootup. I checked the power supply and ended up replacing it. I then turned it back on and still nothing. Power is getting to the system I can open and close the cd-rom drive, and the hard drive is spinning. The fan on the processor wil start then just turn off. I have changed the memory also. Any ideas would be greatly apperciated.

Do you get any beep codes? if so what bios are you useing? Do you get any picture on screen? Bios info or such?

Changing the power supply was the first thing I would have suggested. At this point, I would suspect the motherboard. I've seen bad power supplies smoke a mb, and the symptoms are just as you described (cd working, hd spinning, fans whirring, etc.)

Sounds like the MB is fried. Do you have another PC that is working to snag the MB and install it on the troublesome PC??

This could be a few different things:

1. Can you see the bios screen (any video display?)If not, check the video card (re-seat or replace it).

2. The fan shutting down, if this is a laptop computer with the newer style of processors, it shuts down by itself when the computer doesn't need it. When the computer get warm, the fan kicks back on by tempature controlling.

3. If not the above, then you could be looking at a Mboard failure as to not accepting the correct voltage to the fan. Most computers will shut down or not load without correct voltage.

4. Also, this could be linked to bad boot.ini file on the OS. Making it unable to load the start up files. Have you added any new hardware before the crash? If so, systematically take each one it out and then try to reboot the machine.
