My friend called me the other day saying when he turned on his computer nothing happened. He said the fan turned on and off and there was no power what so ever. I told him to unplug everything and try it in a different socket but he said nothing worked.

So I ordered him a power supply. Go to put it in today and the computer turns on, so the PSU is fine.

The problem is there is no display which he just tells me now. He connects the computer to his 50 inch something TV. VGA to VGA.

The computer is a few years old. HP pavilion something AMD dual core. No HDMI and no graphics card.

He has no monitor or extra computer stuff at his house so I brought it to mine.

I hooked my monitor up DVI to DVI and it worked fine.

So is the VGA port on the motherboard dead or is the VGA cable he uses to go to the TV dead?

I checked the connections and they were fine. He's had no problems for x amount of years he's owned the computer.

"He connects the computer to his 50 inch something TV. VGA to VGA. " LOL, double check that he hit input select on his big screen to get to the VGA input.

If he has a 50" TV then it has an HDMI port. If VGA won't work then buy a DVI to HDMI cable. The signals are the same, the cable jsut moves the pins around. Really cheap. I use them to drive my plasma TV (no VGA input) from an older PC (DVI no HDMI). Works great. But first verify input select on TV. Sample cable: $9

I don't know it's a big ass TV. I don't own a TV.

Secondly his computer does not have HDMI as it's older. AMD Dual Core years so circa 2k7.

Already went through the inputs multiple times.

TV works fine. Satellite, cable, etc.

"Secondly his computer does not have HDMI as it's older." Yes, got that.

You said you test DVI to DVI monitor and it worked. So DVI works on the computer.

Now take DVI out from the computer and put HDMI into the TV. If DVI to DVI worked when you tested it then DVI to HDMI should work to TV. That what the DVI to HDMI cable is for.

I don't have a DVI-HDMI cable.

Also found the problem. The VGA cable was dead. I tried another and it worked fine.
