nilayz Posted September 25, 2005 Share Posted September 25, 2005 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?

interval Posted December 6, 2006 Share Posted December 6, 2006 Any idea what might have gone wrong? Could be something dead on the motherboard, or the processor itself. Try swapping it out. Quote Link to comment Share on other sites More sharing options...
surfcss Posted December 6, 2006 Share Posted December 6, 2006 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.

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. 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.

Quantum Media LLC Posted December 26, 2006 Share Posted December 26, 2006 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 Quote Link to comment Share on other sites More sharing options...
open Posted March 5, 2007 Share Posted March 5, 2007 pulling out the bios chip and reinserting it may help also i had that problem before losses conection for some reason Quote Link to comment Share on other sites More sharing options...
TechTroll Posted March 11, 2007 Share Posted March 11, 2007 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.

topgun23 Posted March 12, 2007 Share Posted March 12, 2007 Would also try another power supply. Quote Link to comment Share on other sites More sharing options...
Mystical Water Posted March 28, 2007 Share Posted March 28, 2007 Well i guess he is right, maybe the motherboard isnt supporting it. Quote Link to comment Share on other sites More sharing options...

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.
