■ So I just bought a new graphics card (Nvidia Geforce gt 630) and installed it, but I'm not getting any video signal. So I took it out and put the old card (I believe radeon 5450 hd or something) back in. The old card is not giving any video display now either. I also cannot use onboard graphics because I believe the onboard graphics have never worked. Weird, I know. Please help, this is my first time I've ever messed with the insides and I'm terrified that I've destroyed my whole pc.
Few other little facts, my computer was working completely fine before I took out the old graphics card, so I don't think it would be the motherboard. Also, I use my tv as a monitor and it only let's you change to a specific channel if there's a signal. When my computer is on, the channel for hdmi (which my pc is plugged into) shows up. So some sort of signal must be going to the television, just no display.
