That's why we get a little agro with double posters.

Reply #3 - Today at 4:43am    the fans only got loud when the computer is first turned on, and then it gradually dies down.The monitor stays blank even when the computer is first turned on. but I dont think its a problem with my monitor, i think the computer itself is the problem.

Noisy fans at start up are common.
I think you may have led everyone down the wrong path by not mentioning that the noise disappears in this thread.
Carry on troops but I'll be watching. LOL!

The motherboard is basicaly what everything in your computer connects to. It is home to the CPU, the RAM, the Northbridge and Southbridge chipsets, the PCI (and ISA if your board is old enough), I/O ports, transistors, capasitors, ect.

Here's an image of a Motherboard that uses a socket 478 processor. Yours should look similar.

Before you do something as drastic as remove the motherboard, please anser this: Do you notice these fans getting loud(er) again when loading a large program? If so, that's the clincher. If that's true, your PC is normal.

Ever open the case before? Know which card is your video card? Make sure that it's in its slot nice and tight. Maybe its just loose.

The next thing I'd do is what Flame suggested above.
Did you do it yet?
