My computer is slow!! almost 5 hrs to put windows on it?

after on my desktop one day it just started running real slow, after a week trying to figure out what the problem was i could not find anything, so i backed up everything and reformatted and installed a fresh copy of windows xp pro, well after 5 hrs it was finally complete still slow as it was before the reinstall. it has a pentium 2.0 ghz and 512 ram 120g hard drive and overall it is an ok computer that should run so so much faster than what it does, also i changed the hard drive with a new one after the reinstall and there was the same problem, i am thinking it might b my power supply but wouldnt it not work at all if my power supply is bad? so please tell me what is the problem with my desktop.

5 hours to install Windows? Download this free hard drive benchmark program and test your speed. Be sure to run the Error Scan test. It could be that your hard drive is not running in DMA mode. Check the properties your primary IDE controller in the device manager and see if it is in ultra DMA mode 5 and not PIO mode 1. Make sure you have the latest BIOS for your motherboard also.

Those Porno sites have viruses U know!
If in doubt replace the power supply. A faulty power supply can slowly destroy the motherboard, before the power supply completely dies itself. Replacing the power supply is both cheap insurance against its failure as well as the only way, other than a meter, of deciding if it is faulty.

YOU HAVE TOOOOOOOOOOOOOOO MMMMAAAAAAANNNNNNNYYYYYYYYY PPPPPPPPPPPRRRRRRRRRRRROOOOOOOOOOOOGGGGG... your internet is slow,or there is too much spam or pop ups,NOT VIRUSES!!!!!
I've heard of this, but I've never seen it. A virus may have invaded your BIOS. How you rid yourself of this is a new mobo, or maybe you can send it into the manufacturer to diagnose. A virus in the BIOS are particularly destructive.
Get a Mac. Then it only takes 30 min to install.
