So i've had this rare random blurry screen issue that appeared at very random times - just browsing internet, or while playing games. Everything is normal and suddenly all the graphics goes to hell - can't really explain , just look at the pic i uploaded - i took this pic with a 20MP phone camera and what you see is exactly what i see.

I was thinking it was just random driver glitch at the start, but over the last 2 months its getting worst and worst. This week my pc froze 2 times, I had this visual problem that you see on the picture above quite a few times, and for the first time now, I also experienced the screen becoming light blue (while sound etc still works on the background).

Restarting the PC is the only way to solve the problem.

I do not have any overclock on the CPU or the RAM and having the GPU either overclocked or not doesnt chance anything.

I've also formatted the PC 2-3 months ago, I had this issue very rarely before formatting too, but I never remember having it in Win7 (6+months ago).

Bad GPU? Which driver is known to be the most stable for gtx900 cards? maybe i should roll back to 6+ months old drivers

Edit: forgot to mention that also the screen flickers/turns black just for a second and then its back to normal (either in windows or while playing)

I would first check the quality/seating of whatever cable you are using. Looks more like a "bad connection" than any kind of GFX artifacting in the "normal" sense.

I've tried reseating the card several times in the past months, it doesnt seem to solve the issue. Just to be sure I will change the PCIE power cable

Try this for as test - uninstall the driver and use the iGPU on you CPU (if you can do without gaming for a few days). That will identify if it is in fact a gfx card problem.

No I was more talking about whatever DP cable you are using between the card and the monitor

It happens I have 3 DP cables (1 from monitor, one I had from dunno where and one longer i bought online). Tried all 3 and still have the issue.

Not to mention that if this problem happens, disconnecting and reconnecting the DP cable or even gently pushing the GPU into the PCIE socket or gently pushing the PCIE power plug on the side of the card doesnt solve it. It only goes away with a restart (unless PC freezes, then just reset)

Im inclined to believe its a software/driver issue, but I really cant find anybody on the internet that reported the same problem apart from noobs having the wrong resolution or people who overclock their monitors (similar visual problem)

Well that is me stumped because to me that just looks like a poor connection rather than a symptom of a broken GFX card. Tried the other DP ports on the card too?

This maybe a weird suggestion, but have you treid turning G-Sync off to see if that changes anything. I don't know why that would do this but the issue seems a bit odd to me and that could just help eliminate possible sources of the issue.

I'll wait to have this problem happen again now that I've just reseated the GPU and cables and I'll try that right after.

I don' t remember having this issue before nVidia introduced the driver that allow GSync in Windows Aero as well as windowed game. I guess rolling back to the driver before this change is something i must try too.

Hmm now I'm worried about mine.... I have an MG279Q, so basically the same panel only Freesync...
Well if my problem comes from the implementation of GSync in this monitor, you have nothing to worry about... Asus rog Swift forum is full of rage about PG279Q issues and actually a few PG278Q (my screen) but I didnt see any MG279Q thread....

I actually called a guy I know who (I just remembered) has the same GPU and Monitor and he said he had this issue since he bought this monitor and he "fixed" it by leaving the screen at 120Hz...

According to him there's something wrong when VSync and 144hz are both on.

So i either have to disable VSync in game-specific options in nvidia control panel (which explains why in CSGO and Rust i never have this problem since i force vsync off in these two games)

Or have 120hz permanent since there is no way to disable VSync in Windows Aero...


8 August Update: Didn't have any problem in the last 3 days (crossing fingers rly)

Things I did to troubleshoot:
-Gave a little more voltage to the cpu (from 1.14 to 1.16v) (4790k stock Ghz but reduced voltage cause it was auto idling at 1.4v lol)
-Lowered ram cycle to 2T (had it at 1T for the last years on previous systems too)
-Re-seat gpu and changed every PSU cable i could
-Changed GSync setting in nVidia control panel to "full screen only" as it was "windowed and full screen mode"
-Still running at 144Hz

Any thoughts appreciated, meanwhile I'm trying to isolate the issue

Edit: forgot to mention I switched PSU mode from passive to active, so now the PSU fan spins 100% of the time.
