Hi Guys
I put a graphics card in my PC a couple of weeks ago.

Last night my screen display was playing up a bit.

A few flashes on icons here and there and a few areas of white squares on the screen.

I turned the PC off, and its perfect now.

Could this be a case of an overheated graphics card ?

I have never been into graphics card, as I use my PC mostly for business.

More than likely the graphics card dying. What card do you have, and how big of a PSU?

I'd run a stress test of some sort on it (3d mark is good) and see if you can kill it altogether, then RMA it.

I assume it's a brand new card?

LOL, are you saying the PC is perfect while turned off..hehe or that now the system is reset it all good.....

As Wrat suggested, check power requirements of the card, (manufacturers website) and your PSU rail outputs....!Failing that, check heat displacement inside the case.

Not a Quadro NVS295 is it?

Sounds like the AGP card I had in the other / older PC. Once it gets into windows it looks like the matrix lol. You can see it, if you right mouse on the desktop. Or click anywhere else.

Its not the mobo, because the onboard is fine. But I replaced it with a Nvidia card.

If it occurs after a while when the card has been actually doing some work, then yes it could be. Check how dusty/fluffy it is.

If it's random, well could be a fault.

Thanks guys,

Its been going OK all today.
But I had just put in a third hard drive a few days before.
So maybe that is too much load on my power supply ?

Its a Thermaltake 430W
The graphics card is an NVidia NX8500GT.

Its not dusty.

What I really wanted to know is that dropping out or big square "pixels" a symptom of over heating ?
