My brother joined a program, in the program he received a computer on which he’ll do lessons on. Its been sitting in our house for a long time, and since then we’ve been trying to find a use for it. The reason why its no use is because the stupid pc is blocked from changing all settings and everything, I CANT EVEN GET TO MY COMPUTER! or start, or anything. I tried restoring the system, but I could not get access to CD drive. Any advice on getting this pc to work would be nice.
