When my friend turns his computer on (the only time so far), everything works fine except the screen stays black and it takes about 15 mins to load to load, but after he logs in, everything is slow and he can't left click. Its not a mouse problem because when he drags, it makes the selector box. This happened after shutting down with an unusually long shut down, and GENTLY moving the computer. He doesn't want to open it or try to reset the because he's worried about messing it up more. They keyboard and mouse seem physically fine, just the left click issue. He just tried turning it on just now, and could not login because the motherboard kept beeping and couldn't do anything except move the mouse around. Does anybody know a reasonable cost for a professional repair?
