Problem

[nilayz]

I have an old PIII machine that has been working well. But today when I powered it up, it refused to do POST and there was nothing on the screen. There isn't any problem with the power supply, coz every other device is working (CD drive, hard disk, lan card LED, cpu fan, etc). Any idea what might have gone wrong?

Could be something dead on the motherboard, or the processor itself. Try swapping it out.

Maybe check to see if everythings plugged in at the back?

 

Opening it up and cleaning all the dust out with a vacuum cleaner usually works. Btw, dust is a conductor of electricty, mabye hard to believe, but it is. Been proven.

Unplugged cables would not create a post-level failure.

DO NOT VACUUM THE INSIDE OF YOUR COMPUTER. This creates electrostatic discharge that will usually fry things. Instead use compressed air specifically for cleaning electronics.

 

Also, dust is an electrical insulator, not a conductor. Usually the only problem it creates is that it insulates heat as well, which can make components overheat; it can also clog up fans.

what i suggest doing is going into your bios settings and reset everything to its defaults. if that doesnt work i would take it to a repair men lol

pulling out the bios chip and reinserting it may help also i had that problem before losses conection for some reason

It is entirely possible that it is the power supply. Just because the individual devices seem to have power does not mean that adequate voltage is being delivered to the motherboard and the CPU. I would suggest replacing the powersupply.

Would also try another power supply.

Well i guess he is right, maybe the motherboard isnt supporting it.

Try cleaning ur ram and refix it.

Hi nilayz,

 

can you post more details about error messages, such as if there's Bios screen which show some memory and harddisks infor? if yes, then it might be your MBR problem. if not, then it's possible some error on your BIOS.
