Samsung Monitor causes CPU to shut down

[pk8147]

My monitor and computer shuts down after approx. 20 minutes. I have narrowed down the problem to the digital cable; if I unhook that cable, the computer will stay on. Once I hook in the digital cable to the video card, the computer shuts down after approx. 20 minutes. Help, please.

Get into the power/ display settings and reapply them. What Operating System are you running?

 

[pk8147]

OS is Windows XP

I have re-applied the display settings several times via Windows....not bios.

I have narrowed this down to the DVI cable. Computer will boot and stay on, but as soon as I hook up the DVI cable, it shuts down within 1-3 minutes.

Can you try using another DVI cable?

 

[pk8147]

Yes. I will try that next.

I hooked up the monitor to an older computer, using a VGA cable.....and it worked fine without shutting down after 2 hours.

So, a new DVI cable might do the trick. Thanks.

New DVI cable doesn't help.....still shuts down.

New video card doesn't help.....still shuts down.

Any suggestions? Thanks.

The PSU.....?

That's what I was thinking captaincranky

Nope....it is apparently not the PSU.

What next?
