Hello!

   Recently I installed a new video card and ever since then several of my programs cease to open and installing new ones (games ect.) don't seem to work either. I first noticed it when I tried to open Photoshop. The splash page opened and it started initializing. Just before it was about to open, an error message popped up. "Adobe CS5 has stopped working" it continues to go on with the typical Window's spiel, "Do you want to send the INFORMATION blah blah blah" but never TELLS me what the issue is. At first I thought that it was just Photoshop. Then I tried Illustrator. Same thing. Flash. Same thing and so on. I attempted to install a game. Never let me GET past the first setup screen. VLC player ceases to work too. The same error messege pops up "Such and such has stopped working".

    Mind you the computer is running GREAT. I've had no other problems with it. The internet works fine, other games that are currently installed still work, better even. I am pretty certain that my problems lie with my installation of the card somehow. Putting it in was pretty simple, I had the extra power ports it needed, everything fit where it needed to go. I uninstalled all of my old video card drivers before putting it in and I've since uninstalled and reinstalled the new video card's drivers from NVIDIA (and EVGA when the first did nothing). I've updated my OS, uninstalled and reinstalled programs that weren't working, nothing seems to help. I've scoured the internet for somebody who's had the same problem but I've come up with nothing. If anybody has some other suggestions I'd be very appreciative. Here's my specs below.

Here's a link to HP's full spec listing if that's better. Everything is the same except for the new video card.
