Let me give you it's history..... this computer was having problems and apparently had it's power supply replaced. When the people got it back it still wasn't working perfectly - the cd rom drive wasn't working. Before they gave it to me to replace the cd rom drive it was freezing up on them and they would have to shut down. When I got it...it was doing the same...Windows wouldn't completely load the background pic would come up but not all the icons. It has deteriorated from there...one time when I turned it on I got streaming letters and numbers and lines going through the screen to now nothing but blackness. Sometimes it will say that the monitor is not hooked up when it clearly is. Any ideas? could it be a virus? I took out the hard drive and put it in another machine to test to see if that was the problem but it just comes up Operating System not found. (operating system is Windows XP)
Hope someone can help.
