Thanks for answering all my other questions, all you guys that have helped I have learned alot from this forum. I have two questions to ask. first I was asked by my friend what is the first thing you do when you have a computer that freezes. And second which is totally a diffrent system I have a system that when hooking and unhooking usb devices the devices after they're unplugged don't seem to go away from the device manager, what can that be? Again thanks.
