hello, i had a problem with my network card, it just stopped, i tried changing slots and taking it out then putting it back but it did not help, so i changed the network card and turned on my PC, WinXP tried to install the network card driver but for some reason it did not install properly. I restarted my PC and i got the "beep" when it booted and the screen stayed black. And now i took it off and working on the built-in graphic card of the motherboard. Can you help me to fix this problem?
