I've looked around on the forum for possible reasons of the freeze and nothing seems to work and so I though I'd post my problem and see if anything relevant turns up.
Around three days ago, while working normally on my laptop, it suddenly froze. By freeze up I mean : the screen sits idle, the mouse does not move, does not react to the keyboard, the hard disk makes no sound or no light to show activity. So I turned off the laptop and couple of minutes later restarted it. It worked fine for a few minutes and then it froze again. The strange part about this is that it happens randomly. There is no specific task that I am running or doing that causes it to freeze. I've restarted it a couple of times and each times it happens. I have tried to experiment with a number of things and it freezes up at different times and different places. This has happened on the welcome screen, safe mode, while logged in an account etc. Basically it happens everywhere. There is no specific time elapsed that it freezes as well. THe fact that the hard disk is not doing anything is what I find really strange. Its not like its stuck in an infinite loop or processing something that would cause the freeze.
So if anybody has experienced such a thing or knows of any virus/spyware that could be causing this please help me out. THe computer is very important to me!!!!!!
p.s. THe laptop is 1.7Mhz Toshiba Satelite Pro 256MB, 40 GB.
