Hello,
I have an HP 700-074 with an integrated graphics card. I recently bought a PNY Geforce GT 630. I first deleted the current graphics card from device manager, then installed the new graphics card and drivers. When I hook up a DVI cable to my monitor it seems to work fine...But when I hook up the HDMI to the monitor or my TV I get "No Signal". A few times I restarted my computer and my TV would display...But after the HP logo it goes off and back to no signal...Any ideas on how to fix this and use my HDMI? I want to connect my computer to my TV which doesn't have DVI so I need the HDMI to work. Thanks!!!

I hate to play captain obvious but did you switch the tv's input or source to the proper hdmi port?
If so then it might be a resolution or refresh rate issue.
Hook the dvi back up and on the pc select a resolution and refresh rate supported by your tv's hdmi input. You'll get those from the tv's manual.

Yes I have made sure it is on the right input and even changed HDMI cables. I also tried the HDMI on my TV and monitor and it wouldn't work with either. I also made sure my refresh rate and resolution rates were correct. On a side note...I tried restarting my computer and there was a small update...And my TV was on and showing the update the whole time...But once again as soon as the computer loads past the HP logo, off it goes. When I check out device manager it just shows the one device...Nvidia Geforce GT 630 and not my original integrated graphics card.

Update: I had my TV and monitor both plugged in at the same time but only the monitor was displaying. I downloaded another driver (I think it was just a beta) but as soon as it finished my pc displayed on my TV! I used it for about 30 mins without a problem. Just making sure it was good I unplugged the HDMI cable and plugged it back in...NOTHING!!! I then tried connecting to my other tv via HDMI and it worked fine. I then plugged in HDMI to my monitor and it also worked fine. I tried both HDMI ports on the main tv but still nothing...But with my blu-ray plugged in it works without a problem. Am I missing something here?!
