Graphical glitches with new graphics card

Recently I bought a new graphics card: GTX 960. I optimized the game settings and installed the newest drivers. But now I'm getting strange graphic glitches mainly in games (CS:GO, BF4) but sometimes in the browser too. The glitches happen on the edges of objects, ONLY when I move in the game. They are blue,green,red,yellow scattered points showing up only for the time im in movement and only on the edges. Also, I can't screenshot it, cause they dont show up on screenshots. I tried changing the HDMi cable, nothing. I was thinking, can it be related to the power supply not being able to give enough power to the card? There's a 50W difference between the total power of the PSU and the power need for the video card.
Do you know anything that I could do to fix it? Thank you in advance
Specs:
i5 4440 3.1ghz
Win 7 64 bit
8 gb ram
Nvidia GTX 960
1T HDD
motherboard: Asus H97 M
Also a soundcard

Rule of thumb

In reply to: Graphical glitches with new graphics card

PSU outputs x-watts, the GPU needs x-watts, but guess what, the whole PC needs x-watts on top of what the GPU needs. Also, if you didn't know the PSU maybe rated for x-watts but THAT isn't a constant output but "peak output" demands. Also, the typical rating should be more in line with 75% of the rating and that should be used to suggest what the PSU really outputs and hopefully at a stable level. Alas, heat WILL!!! degrade that output and drop depending on the quality and power scheme of the PSU. Thus, it usually pays to buy a PSU that is at least 100W over what is required, be single rail and QUALITY build, likely from a known name brand. Bigger is better and best cooling is also a must not only in the PSU itself, but the case as well(airflow).

Use the PSU calculator at some website, add 100W; check that out.

At a minimum you need a 500w single rail unit.

What psu do you have....make+model?

I agree, what PSU?

"There's a 50W difference between the total power of the PSU and the power need for the video card." tells us you may be pressing your luck.

While driver glitches are FAMOUS I'll share that I am using Nvidia's Geforce Experience to keep the drivers up to date with good luck.

In reply to: PSU

First problem is that's a 350w unit.
Second problem is it's a dual rail unit.

Shop for a 500+w single rail psu.
