I have two computer, both with major problems.

Computer one: To start with, each time I start windows XP Sp2 (the only I got) my cd-rom cant be found. Each time I got to go to controllpanel and install it everytime I start windows, and after that it works just fine. I got 3hdds and one cdrom.
And my CPU is a p4, and it gets overheated all the time, starts in 60 or more..


Computer two: It "hangs" itself, while working, could be anytime it just locks, cant move my mouse or anything. Cant find any reason why, so I though it would be the software because hardware problems usually reboots when they are having problems? I cant reboots if I dont press the reset button on the computer. I could be playing a game, or just typing, or just doing nothing.

*Forgot to mention* Windows XP SP2 on both computers, and I have had bad experience with it before, but never knows what to do.

Guys and girls, please help me, hope you understood my problems, I'm not used to talk about computer in English since its not my first language.

Admins, if this is the wrong place for this tread feel free to move it since I dont even know where the problem is...
