The TV tuner and video and audio inputs in my AIW Radeon 7500 just stopped working. They were working fine earlier today and when I pulled up my TV tuner a couple of hours ago I get a black screen. The same with the composite input. When I turn it on there is a blip of TV sound and then silence and black screen.

I haven't done anything new except hook up my VCR to the Composite in plug yesterday and it worked fine. I scanned for viruses, rebooted numerous times and turned off the computer to let it cool down; the cases temp is 30c and CPU is 35c.

The only things I can think of are that the tuner has died or I have overtaxed the power supply. I have 3 optical drives and three hard drives. I have an Antec 430w power supply, Soltek75frn2-l mainboard, AMD 2500xp Barton CPU, 2 case fans and 2 video cards: the AIW 7500 Radeon and a PCI Radeon 7500 running on Windows 2000.

Any help would be appreciated - Paul
