Screen works fine until Windows loads
I assume it's an issue with my refresh rate. When I turn the laptop on, the bios stuff is all displayed normally and just fine. When windows starts, I see a little blue bar about 10px at the bottom of my screen that extends all the way across. This occurs whether I use safe mode or normal mode. The windows display never covers the screen. If i plug in an external monitor, it's just a blank screen. It must be a software issue?? I've never seen anything like this, and the computer worked a couple weeks ago, the last thing I can remember doing is installing network card drivers for a mini-PCI wireless card. But if this was the issue, I thought that surely safe mode would work. HELP!!!
