Odd flashes, hardware or software, your 2 cents...

At my PC
Just wondering if people could give their own advice on this, I've got the specs in my sig, I've got nothing O/C'd and no issues with heat, (my CPU for example idles at 15^c and loads to about 25...)
Every now and again while playing games however, I get sudden flashes where its seems that the screen the has gone mental.. It doesn't cover the whole screen, and it doesn't seem to be certain textures or renders, its just like bands of the screen flash like a brown... Now it hasn't always done this, and it seems to be indescriminate as to game too, occuring on anything I seem to play...
It doesn't seem to get worse with time, as flashes can occur 5 minutes in and then not occur for half an hour and then flash again...
Currently up-to-date on Drivers and am just a little confused...

Any extra info required just ask...

doesn't seem to affect frame-rates or anything either...
 
Sounds like GPU artifacts. Try running a GPU stress test like Furmark or MSI Kombustor.

If your GPU is artifacting without it being overclocked then there's a hardware problem there somewhere, possibly PSU related, or your GPU is faulty.
 
nope, just the DVI... Have gone on Furmark for about 5 mins, seems to artifact when post processing effects are on...
admittedly not a long test, but let it get to what seemed to be a max temp, then tried the post processing and it got to a max temp and seemed to start artifacting, turned off the post processing it seemed to stop, turned it back on and it seemed to start again...
a nudge toward CPU problem?
 
I'd have thought a 700W would happily handle what is in the case, only like 2 years old this Christmas if memory serves... possibly 3 i guess. If downclocking the GPU works, I'm sending it back, I had a factory overclocked 3870 from HIS before this card, and that needed downclocking too, and I was really upset by it.

running Prime95 stress tests now to test the CPU...
no issues so far on test 8...

artifacting at stock clocks sounds like a faulty GPU. Can u post a photo of the artifacts.

Can't really as they occur intermittently for split seconds.

The most probably cause is the overclock on your gpu.

try to put the gpy back to stock settings, and see if issues dissapear...

Please read threads before posting. There is no O/C as stated in OP.



It's really odd. I just loaded up Starcraft 2, some mild artifacting while navigating just the menus. play a 1v1 that lasts about 25 minutes and not a single problem.

Its so oddly intermittent, I'm not sure what to do about it!
 
I believe this is an ATI driver issue as I have the exact same thing happens on the desktop as well maybe once or twice a night.
 
I have been toying with the idea of a re-install to try and re-arrange where my data is on HDDs. Might help, might not...
 
Go to CCC and under the 3d effects have a look at the fountain render, does it do it there?

If so I think ive had the same problem, knackered GPU, OCUK currently in the process of replacing it.

I had a similar problem with my 5850 after updating drivers a while back to 10.4 but mine wasn't when gaming it was on desktop when flash videos were involved. I would get a line flicker across the monitor. Ended up having to disable hardware acceleration in flash video settings to stop it. Was damn annoying and haven't been able to find a driver since that allows me to enable it again. (not that it seems to make much difference anyway)
 
fairly sure my issue only occurs after putting my PC to sleep and waking it back up again, a full restart seems to clean the issue. More than likely just a software issue somewhere, be it windows or a driver...
