Hi,

Today my computer started displaying a thin column down the right side of the screen, made up of short horizontal lines of coloured pixels, flashing and changing colour in response to the position of the cursor/other windows.

I assume this is a GPU artifact, so I checked the temperature (30 degrees) tried cleaning and reseating the card, and checking all the cables, but to no avail. The only thing that gets rid of the artifacting is setting my desktop to 16bit colour mode for some reason.

Am I correct to assume that this is a graphics card failure, and my only option is to replace the card? The card is a 'XFX HD 7770 DD' only 1 month old as I just bought it to replace a failing 5770. I assume it will be under warranty through ebuyer so not costly, just a hassle if so.

Thanks for any help.
 
It might be your monitor.
My old 30" would have a line or two of pink vertical pixels when i would start it up/wake it up from a long sleep. they would go away after a while though...Just got 2 24" monitors for like 1/4 the price i paid for my for 30" when it was new...

The 30" was beautiful to watch stuff on.
2560x1600, I'll miss you.
 


I would check with a second monitor as well to eliminate that as a possibility.

You should check out the great selection of Korean 30" monitors. Decent price and they look beautiful.
 


I'm almost certain it isn't the monitor, as I just tried running a game and the artifacts were different - typical white/black boxes, stretched textures, white flashes etc.

I bought it on a recommendation from here 3ish years ago, pretty sure it should be plenty? Had the whole system stress tested at the local computer shop a month ago too to make sure it was just the old card at fault so it should still be running well. Do you have any reason to suspect it isn't simply the card at fault, other than it being new?
