Celeron G540 artifacting on desktop and videos???

post #1 of 4
Thread Starter 
I have it in a little backup rig, all new PSU, ram, mobo, I might have used it for a full 10 days in total so far since last year.

Its powering a 1280x1024 LCD and as of today I started noticing little white dots flicking around just on the win7 background and on a few 700MB videos. They don't last long so far, less than a minute then disappear.

Sure the iGPU is weak but that still doesn't seem right

Does the iGPU use your standard RAM? My first thoughts go to a possible memory issue, and I'd be tempted to run memtest or a similar memory test to check the RAM is OK. Second thought would be a driver issue, and I'd try different drivers. Other than that, it could be that the iGPU is faulty.

Edit : oh,and I would try a different monitor, just to eliminate that as the issue.

Come to think of it AMD drivers are also installed besides the intel ones, could be that


I uninstalled the AMD drivers, same issue. As far as I know it doesn't use the system ram.

hmmm, it's just that most iGPU's use the system ram, which is why they're never as good as add in cards with their own memory. Artefacts like dots or stripes usually point to a hardware problem, whether it be faulty memory, a GPU that's disconnected from the board (thats why many try the bake trick) , or an overclock that exceeds the GPU/memory capabilities.

It is possible its signal noise if you are using a VGA connection rather than a DVI/HDMI/displayport. That would produce more random specks, if its more uniform/repetitive, i'd be looking at the graphics hardware.
