Freezing screen & cursor sometimes Stops altogether blue screen appears?

My PC screen %26 cursor freeze and sometimes the screen turns blue and shows a 'STOP' text amongst other writting, it says 'your system has been shutdown to prevent damage to ur computer...etc;' In both instances i have to hold in the button on tower a while then again to turn it on. Although these 2 problems don't occur often and i can't see a pattern, it worries me. Do I have a virus? Don't have much work etc saved on it, simply because i know nothing about computers to do it. Have Panda Titanium antivirus and generally just download n save music once a while on Limewire and browse the internet just 2 familiarise with it. It's a Dell Dimension 8400-Windows XP- Home Edition HT- Microsoft works- 512 MB- 160 GB- 128 MB video card. What else can i tell you. I bought it in 2004 (Yes, i know, long time) but never opened it due to house renovation and just got connected to internet a month ago. Most of the time runs fine. I do a defrag, although some files are not done and i scan it too.

First things first, Limewire is a bad place to get music from. Honestly you should get a account with like Napster or something, i know you have to pay for it but its worth every penny and you wont get in trouble for downloading illegal music files. Second off, what you need to do is a repair of windows, if you have your windows cd you need to boot from it and choose to repair windows. This could be quite a task if you dont know too much about computers, so if it would help you could take it to a computer place and have them do it for a small fee im sure. As far as it being a virus it could very well be caused by that but generally its because windows is missing a file or something isnt functioning correctly.

I must disagree with you xFS.Mirage. The problem he is having is as simple as a bad memory stick. I'm a tech and see this problem all the time, and it's always related to a bad memory bit causing Windows to scramble and crash with a blue screen.

Download this free memory test from http://www.memtest.org/ and see for yourself. If I'm wrong, my apology to xFS.Mirage
