I came over to my friends house to help him with his pc, and he was getting a no signal error from his video card. So i tried resetting the cmos, and blowing out the ports and such, same thing. I took the cable and tried each port, same thing. I took the cable to my pc, worked fine. I took the cable from my monitor to his pc, same thing. So i took my hd5850 out, put it in his PC, same thing no signal. i put his 9600gt into my pc, worked great out of ONE port. he also complained of his keyboard and mouse (both ps2 connections) going out every once and a while. Also, his on board video would give no signal as well, vga, and dvi ports. New motherboard time?
