so my friend's machine died. It is a Emachine T2482 with lots of upgrades. When i got it it wouldnt even respond to the power button so i replaced the psu. So it turns on now, but im getting no video. I've tried the intergrated one, which i dont think was working before i got it. I also tryed an AGP card and a PCI one non of them have worked. I also tryed reseting the bios. any ideas on what to do? is the motherboard dead? I hope not.
