I've got a TV card in my computer that I never use so I'm going to try and sell it. Its called a "Video Mate E700". There is a cable that runs to the top front of my machine, I was presuming that it goes to my headphone or microphone jack? And theres another cable that goes to the motherboard, I think its labelled "Power SW".
I was wondering if I can remove both these cables and sell them with the TV card, or do I need to keep them and plug them in elsewhere?
You should have uploaded it anyway. It will surely help. Why the Power SW goes to the TV card is beyond me. It's normally connected to the motherboard, and I've seen it that way for a looooong time.
The other gray round cable could be headphone/mic jacks. If you can, upload photos of the headers themselves. Unplug them, take a picture of the connector, and plug it back in. So we can identify the plugs.
It's a bit too blurry, but I can make out the headers. They are the Power SWitch, and the Power LED. The Power LED indicates if the PC is on or off. You can place both of those on the pin area on the bottom right of the first image you posted. It's the area with a distinct red and green wire.
This image should aid you in finding out where to place the wires. Note that if the Power LED doesn't turn on when you turn on the PC, just reverse the two Power LED wires. They are picky with + and -.
Just a bit confused, if the round grey cable goes from the TV card to the motherboard then surely it wouldn't connect the motherboard to the motherboard? Wouldn't I need to move the end thats currently in the video card to a different position?
