My old video card (Nvidia GeForce 8500) overheated and stopped working. I ended up buying the Nvidia GeForce 9800 GTX+. I just got it this morning and installed it. I think I have everything plugged in correctly, but I am not 100% sure. When I tried booting my computer up all the fans were working, but my computer didn't start up. On my monitor it said "No input signal." I've been trying to fix this for the past few hours now and I've exhausted all possible options. Can someone please help me? I have a HP m8000, I can try and find any specifications if needed. Thanks for your guys help!
