In this question:http://www.experts-exchange.com/Hardware/Components/Video_Cards/Q_24397963.html
it was established that the reason my monitor isn't working is either:
1. Bad graphics card
2. Bad power supply
I have a new graphics card, but the first thing it says is to uninstall software from an old graphics card. I can't do that if I can't see the screen. Any advice?
Further, if it turns out not to be the graphics card, is there any testing I can do to determine which of the other two it is most likely to be? I know that when I power it up, sometimes all the fans come on, sometimes only the one on the power supply itself. Thanks!
