Author Topic: Computer hardware problem...?  (Read 3040 times)

'Ello again guys. I just have a small question about my computer's hardware, as i have been encountering a problem with it lately.


I recently bought my computer, just about 4 days ago from Newegg, and it started off beautifully, and still is working wonders. There's just one problem.

My computer runs fine from start-up, and goes for about 5+ hours running normally. But after a certain amount of time, strange artifacts start appearing all over my screen, and it gets to be quite an annoyance. The only way i can get rid of them is to shut down my computer for a while, and then they go away for another short period of time.

So this is what i ask you, what could be causing it? It isn't the monitor, or the cable. I've narrowed it down to either the GPU, or the PSU, but i just need to know which is causing it. The GPU isn't overheating, because it's running at a nice 50 C when i looked, while the artifacts are on the screen. I also have updated the drivers, and even re-seated the GPU, which hasn't fixed it.

So what could be the problem? Just ask for more details if you need them.

Also: I managed to get a screenshot of the artifacts,

It might be because your graphics card is probally too hot.
I'm a idiot.

there is absolutely no way a psu can do that
pretty much all artifacts on-screen are caused by the gpu

I want to say it's the PSU because the card may not be getting enough power.... but if that were the case, wouldnt the artifacts appear right off the bat instead of 5 or so hours into running?

Search Google for people who have had similar issues with their graphics card.

Already have, seems nobody has my exact issue.

what's the psu model/wattage

GPU is an AMD radeon HD 6450

PSU is 300W

Do you have your graphics card set to overclock mode? If you do then change it to a lower setting.

It's as underclocked as i can make it, still happens

Normalclock your memory shader. If it's already on normal, underclock it.

LOL yeah get a new PSU. I have a 450W and it has trouble powering my rig.

HD 6450 recommended PSU is 400W.
Though for normal use / low usage it shouldn't bring problems unless it reaches peak power, which it definitely is not the case.
