you probably don't need a new screen it's probably your screen inverter that's going. It's just a small strip at the bottom of the screen wjth a little circuit board. If you google screen inverter and the make and model of your laptop you'll see what I mean.

The Windows operating sustem appears to be corrupted and most like to get a working computer you need to restore it back to the factore default condition.

Hi Sam,

What operating system are you using ?

If you remember what time it last randomly shut down on you, use the system event viewer to see what errors were given just before it turned itself off. You can access the event viewer in Windows XP by clicking on the Start button, then click on Run, and in the box that pops up type in "eventvwr" and hit enter.

Click on system on the left hand side to view the log files of the system. Browse down until you find the time when your laptop turned off. Hopefully there is a series of errors there. They should be able to tell you something about why it is doing it.

Hope this helps, feel free to post some of the errors back here if you find any!

It sounds as if you may have spyware of sorts running on your computer slowing it down, possibly a virus or just too many programs running in the background. What are you running as far as Anti-Virus and is that software current (up to date)? You can try some Free downloads to look for and remove that junk from your computer... we use www.superantispyware.com to fix and remove any spyware, malware, trojans, etc. from our PC's. Also, turn off as many programs running in the background as possible and make sure if your on a network (home or office) that is is secured. So that no one outside can piggy back off of you.
