I am fixing a computer for my friend at work. It is an HP G71 laptop. He was having troubles with it because it would freeze after a few minutes so I re-installed Windows 7 64 bit Ultimate. This seemed to work, but lost the drivers for the wi-fi connection. I loaded those onto it and now it gives error messages when I try to open an HTTPS webpage. Also, I left it running and the screen saver did not work and it seemed to freeze at that point.
I have gotten great help here before and am hoping that someone will guide me through diagnosing the problem.
