Nvidia + Tv Tuner Problem Doing my head in

[selien]

Ok..
First post here, so ill say hi first! (long time reader first time poster ), hope someone can help me out, it would be greatly appreciated!

Ok I am running Win7, I have a winfast TV tuner card and a nvidia pcie gfx card.

Up until recently, I had absolutely no problems with them both.

They ran fine, perfectly.
I have a multuple RCA port station, I have my xbox360 plugged into it and my cable tv also, this plugs into my TV tuner card which accepts the 3 connectors, red, white, yellow and connects to the card as a S-Video
My gfx card utilises its HDMI port to my plasma tv.

So generally, when I want to play xbox or watch cable tv, I will run it through my tuner cards software, winfast PVR2. Using the CVBS channel it will display my tv or xbox, which in turn I can then record etc or display on my plasma or monitor to do what or utilise what I need at the time.

My tv tuner card, sat on the lowest PCI port in my pc, and the cable seemed to stretch abit, so I decided to open up my box and move the card to the highest available port just so I can relax the cable abit.

After rebooting, the devices are still there, I get video from the tv tuner card but absolutely no audio. I have rechecked the cables and everything is connected 100% fine.
Now also, my gfx card wont pick up my plasma, I cant seem to enable my tv anymore.

I tried various things, reinstalling drivers, moving the tv tuner card back to its original port, trying different settings and yes, I reinstalled win7 and now, Im getting absolutely nothing.
I seem to have lost the ability to play audio via my tv tuner card and my plasma is no longer detected.

Does anyone know whats going or what I need to do?

Thanks for any help!

Only piecing this together from past experience, but it would seem that the video driver is the common denominator. Odd as it seems, I know that my sound disappeared when I uninstalled a video driver in preparation for an update. Obviously, it could account for the video problems also.

I would recommend reinstalling the video driver, with the video card located where you intend to leave it, by booting into Safe Mode as administrator, open the Device Manager, uninstall the Display Adapter, select Show Hidden Devices, in case there is any ghosts of the video card, run Driver Sweeper to remove any fragments of the previous driver installation, not touching anything that says VGA, rebooting into Safe Mode as administrator and reinstalling the driver.
