Hello, I need help...Im not sure if my xp has anything to do with this, but at one point my computer wouldnt turn off either, but now I can turn if off but somehow it doesnt want to get into the start up. When I turn it on, it just goes buzz, buzz beep, (delay) buzz buzz beep as if it wants to go beyond the "over range" reading on my monitor. What do I have to do. This started three days ago, It seems as if something is in stuck mode, and the first day this happened I turned off and on a few times and it worked but it goes through this each time I want to turn it on, and Im bummed because that doesnt help anymore and I dont want to harm it even more. Any suggestions?
