My machine was running slow, so I thought it was about time to reformat. I did that, reinstalled windows, updated to service pack 3, did a full virus/malware scan with pc-cillin...and its still not running smoothly. This time, firefox even crashes every now and then, even after reinstall. The main problem is that when I'm running just a few programs (itunes, ie, utorrent), the comp fouls up. I noticed today in task manager, that at one point, the processes that were taking up 99% were rapidly switching between teh different opened programs. Seemed very fishy to me. Here are my spec's 2.0 ghz AMD athlon xp 2400 768 mb ram 2 HDD nvidia geforce 6200 I've had some power supply issues and I will be replacing it shortly. Can a faulty powersupply cause the above problems, as in not enough power to the processor. Is there any software that i can run to check the processor? Thanks, Steve

perfectdark111, could a failing PS cause it? Sure. If that doesn't solve it, take a look @ http://www.computing.net/answers/wi... and see if any of that applies. HTH. Ed in Texas.

Did you install the motherboard chipset drivers?

You mentioned that you use µTorrent, if you are using a firewall other than the XP one, make sure its not creating a log of every connection attempt. If it is this will produce the CPU max out. Kill µTorrent or stop the firewall creating logs to see if that helps. This caused me troubles a while back. Its not likely to be the power supply.
