I have a refurbished computer running window 8. I was running a scan which unfortunately I cannot think of the name of, as this happened over a month ago. What happened is my monitor completely Froze during the scan. after attempting to unfreeze it I must of hit a key that should not of been touched. My computer now will not actually run sorta. the screen is just a bunch of lines with a light brown background. The light on my actual tower will not come on. But here is where I am totally lost. When I hit the start button it sounds like it should well running. And I can charge my mp3 player on it with no problem. But seeing this computer was fairly new I am not able to give you much more of a description of what I am running accept windows 8 and gateway is on the front of the tower. I am hoping someone might have some idea if I can fix it myself rather then paying to get it fixed. Sorry about the few details I am sure that is going to make it harder for you to figure out possibilities.
