HD TV Tuner Issues

[kanimation]

My set up:

Dell Studio XPS 8100
46 inch Samsung LED TV
Ceton infiniTV 4
ATI Radeon HD 5670
(Adding Bowers&Wilkins speakers and reciever)

The problem:

Recently, Media Center only sometimes recognizes the TV tuner and cable card, often won't display a signal, wants me to reset everything up (I've done this twice). Any ideas on what could be happening? The only change I made around the time of the problems was linking my Xbox as a Media center extender through and Ethernet cable to my computer.

Now it fails to work 100% of the time.

Adding more details and pictures...

Check to see if the following update is installed from the "View update history" page.
If not, try to install it.

I downloaded it but it said it was not applicable to my system.

What TV tuner card is installed?

 

[Anthony]

Every now and then it does that with me. The work around for me was to close media center then End the Processes in 'Task Manager'. Then restart Media Center. However since doing a clean install with SP1 integrated, it has not done it yet :huh:

Here are the Processes to kill in Task Manager:

It's an F card.

Mine is the Hauppauge HVR-2250, what is yours from the device manager?

I thought you were talking about the cable card.
It's a Ceton infinitv 4.

I killed then and still no live TV.

Your PSU seems a bit small for that system PSU 350W?

Do you have the latest drivers installed?

Yep, unfortunately that's correct. I questioned that might be the problem.
My friend (Zenix Net) who has the same computer I do upgraded his PSU and it made all the difference in the world for his video card.

The only thing I don't understand is why it worked fine for 3 months with 350W and now suddenly stopped working.

 

[Sardonicus]

Try system restore.

 

[kanimation]

Already tried it, won't go back in time far enough.

Maybe because you added another couple device's to the arrangement? Speakers and reciver?

I haven't added the speakers yet and it worked fine for 3 months when I added the TV tuner. But when I do it would probably be best I upgrade the PSU anyway.
