Hey guys (new guy to the forum). Regretfully I'm at a loss for why this is happening, and I'm hoping someone here can figure it out.
I recently bought a brand new ASUS desktop for a pretty good price. Here are the specs:
OS: Windows 7 x64
HDD: 2TB hard disk
OD: CD/DVD/Blu-Ray optical drive
CPU: 3rd gen i7
GPU: originally an ASUS made NVIDIA GT 520
I later found out that the GT 520 sucked. A lot. So I bought a Galaxy NVIDIA GeForce GTX 560 (factory overclocked). Of course then I realized my power supply wasn't powerful enough to run it, so I had to go buy a new 500w Enermax power supply.
Finally, after lots of time and money spent on upgrading this PC, I thought it was all good. Nope.
The GTX 560 is an awesome card.... and I'm stunned by it's speed and power. However, as I should've expected with my luck, something else has gone wrong.
After 10-20mins of playing Civ5 or TF2 even, I begin to see a shimmering effect occur on the screen where the pixels sort of become distorted (sort of looks like liquid almost). MSI Afterburner was tracking the GPU at running between 60-80 degrees celsius which I must say seems pretty hot, but I'm not sure why that would cause shimmering?
This only seems to happen after the GPU has been in high use, like with these games. Although, I have seen a bit of shimmering for a few minutes after bootup once or twice.
I literally just installed this graphics card today, so quite frankly I'm shocked that everything is going to hell so quickly.
The driver is up-to-date according to NVIDIA and, while I had custom settings to start with, I have since restored all of the driver settings to default, which didn't help at all.
Does anyone have any idea as to why this is happening or how to fix it? Is the card just defective?
