Help! I have a Compaq Presario FS740.... It was recently put into my room by my parents because we needed a new computer. The reason we needed one was because of the FS740. After a while of being on doing whatever, the screen seems to shrink and eventually the monitor fades and goes completely black. I turn the monitor off, and then on, and it goes bright, then dark and again to black. If I turn the monitor off all night and turn it on the next morning it works fine....for about an hour, then the problem comes back!! I know a little about computers but I have never even heard of such a problem such as this, please help!
