Monitor wrecking graphics card?

  pjwheeldon 09:12 07 Aug 2006

Anyone know if this is possible? Have a nephew whose machine has ruined 3 graphics cards. After the last one had a rebuilt, replacing all components with the exception of the monitor, proccessor and the RAM. Machine has worked without problem until 2 weeks age when the graphcis card failed again! Investigation my local PC shop confirmed it had been blown.

My only thought is that the monitor is somehow causing this, but only because I am at a loss to explain this otherwise. Any suggestions or confirmaiton would be a great help!

Cannot see monitor as the cause but, try another monitor if you can

Is it the same PSU?

and does the graphics have it's own power connector.

The monitor is very unlikely to cause this problem, and I heve never heard of this happening, but that doesn't mean it's impossible. There is an electrical connection between the two, so a monitor fault could put an exceesively high voltage down the wire, but I would have thought that for this to happen the monitor would not have worked either.

SG Atlantis

Yes, installed a brand new PSU. First 3 cards ruined did not have a separate power connector (2 6600's and an FX5200). Last one was a 9800 pro which did.

Is it plugged into a Surge protector or straight into the wall socket? Could be spikes coming through the household electrical wiring?

As has been said the monitor is unlikely.

Just to help clarify what was replaced when installing the last card (which subsequently failed):

HDD x 2
Case fan x 2

All new

Re-used the RAM and CPU, and of couse, the monitor!

I gave them a surge protector a while back, so will check that they are using it. In view of the general consensus of opinion that it is prob not the monitor, I was wondering if it could be defective power cables or similar. Clutching at straws now, but might be worth getting new ones anyway, as not a majoe outlay.
