My computer starts but it won't recognise my monitor or keyboard or mouse. I switched out the power supply and that's not the problem. [I know that i have about 7 fans in my computer. (I didn't make it like that, a friend of mine did)] I keep getting this really LOUD BEEPING noise, as though it's stuck on reset. I haven't switched out the harddrive or motherboard yet. DOES ANYBODY HAVE ANY IDEA ABOUT WHAT MIGHT BE GOING ON? PLEASE HELP I'M GETTING DESPARATE! Also before all this started, my CD-ROM wasn't wanting to work. It would let me listen to music and insert a CD to play a video game but it wouldn't write anything or let me install anything or watch movies. (But it used to do ALL those things) I can't do any system restores because my system restore was turned off!
