I have a Toshiba Tecra 8100 that freezes up. It freezes up at random, on any web page or web site, with no apparent reason. I have re-installed the OS(XP Pro), including reformatting the hard drive, so I know it is not software. The only thing I can do is turn it off and start over.I don't know where to begin looking for an answer; Could someone help? Thanks for any advice.
