Sometimes the monitor is blinking

[golemkaaa]

Hi!
Yesterday I replaced the old case of mine with a new one . I have put everything back to its place , turned on the PC and on brown colour I can see that the monitor is blinking , making annoying waves .
In the old case I never had issue like this . Tried 70/72/75 Hz with smaller resolution but the upshot was the same , the monitor was blinking .The monitor is Benq G2222HDL and the VGA is Gigabyte 5770

Ok , I have noticed that when the VGA isnt under stress everything is fine .Tomorrow I will clean the VGA and will post if the issue is still persist.

Did you remember to reconnect the graphics card power connector when you built your new case?

Did you remember to reconnect the graphics card power connector when you built your new case?

Yes . The 6 PIN connector is connected to VGA

Ok.
The state is the following :
Another VGA + My monitor = blinking
My VGA + Another monitor = blinking
Another VGA + Another monitor = blinking
My VGA + My monitor = blinking

Was testing it with this .

My question is : may the PSU cause things like this? Im using an older one , FSP SAGA II 500W .

Try testing with something like Furmark. Something that will really stress your video card. Maybe your PC isn't quite compatible with that test program that you're using.

I dont even understand the whole situation . I just changed the case , not the whole pc ... I will stress it and post the information soon

Sometimes if some electronic device is near monitor it creates problem. So if woofer mobile phone etc are not near the monitor.

There is no other thing except the monitor and the case .Im not using speakers and other thingies .The mobile phone is far away from case/monitor.

Update:
Strange thing , was testing with furmark , not even a single blink
Test results:

At this point im confused totally .In furmark not even a single blink but in games or 720p movies blinking . What should I do then?

 

[Mellon Head]

Well, I'm confused as well. Furmark taxes the GPU pretty heavily.

You could try MSI Kombustor. It's in the Afterburner overclocking suite located here:

MSI Afterburner

Don't screw around with the overclocking stuff in the program, just run the benchmarks and test programs to see if the monitor blinks with it.
