Windows 7 Media Center Problem

[tynesider]

I have a TV tuner but when WMC scans for the signals it gets so far then freezes or my computer reboots itself. I know the signal and hardware are ok and I didnt have any problems a few weeks ago when configured it to the TV tuner.
Is it possible to reinstall WMC or to fix it.
I have been advised to go to Tasks/settings/windows media setup/install, but I don't know how to perform this, where is tasks?
If I install windows 7 from within windows would this correct the problem?

Thank you

Hey i will suggest you to follow the link given below which will guide you for the Windows media center and you can also download the plugin of the same, possibly you are getting the problem because of the plugin not supported the same. So go through the link
WMC

Thanks but it wouldnt install, I got the message Update not applicable to your computer.

Did you checked the network connection setting in Windows Media Center and Internet Explorer? Try to check them, maybe that might cause the above issue. If possible do a clean install after ensuring you have backed up all important files on your PC and I also suggest running the Windows 7 Upgrade Advisor.

I think this is the problem related to the software which you are using to operate the TV TUNER Card in your computer system. So i think you should first uninstall the software properly from the "add and remove programs" from the Control Panel of your computer system. After the removal of this software reboot your computer and after that reinstall this software for the TV TUNER card. After the installation completes, Reboot the system again. This will solve the problem related to the WMC and the TV TUNER card of your computer system.

Thanks, I havent used the software that came with the TV tuner, I used WMS.
It looks like I will have to do another install of Win 7 but thanks for the advice I will run the Upgrade Advisor again first.

Cheers

Thanks Glenny, you were right.

I had the updated drivers installed and thats when I had no problems with the TV tuner,however I found that Ashampoo Win optimizer, had deleted it along with other drivers. I then did a system restore from before win optimizer but its did not correct the problem. I updated the TV tuner drivers manually and its now up and running.

Thank you
Also thanks to all other members who helped me solve this problem.
