My computer was recently upgraded to Vista, and when I set everything up, and turned on the power, I thought it was fine. The power light came on, the fan came on, it was doing all the normal startup things. Except that my monitor stayed idle, and the lights on my keyboard and mouse didn't come on. I have tried different monitors, tried a different graphics card, everything I can thing to fix it. It was working when it left my friend's who upgraded it for me, but not now. I've run out of things to try with it, and I'm ready to throw it out the window in frustration!! Please help!!
