GAMES AND WINDOWS SLOW-MO

[TheDarkTower91]

Hi, my PC is doing really crazy things.

My rig:

i7-4820k (4.5GHz O.C.)

P9X79-PRO

G.Skill Ripjaws X DDR3 1866 PC3-14900 16GB 2x8GB CL9

2x SLI - Asus GeForce GTX780 DirectCU II OC 3GB GDDR5

Samsung 850 Evo SSD Series 1TB Sata3

Asus ROG Swift PG278Q 27" LED 3D 144Hz

Etc,etc...

 

The Problem:

Start saying that this just started recendly, I have been playing Overwatch like 7 days and 4 of them it was smoothly.

When I run Overwatch for some minutes my fps's fall from 130 aprox to 8-15, and they keep there till I reboot. But something really strange happens, if I exit the game and open task manager for example the task manager window is perfectly ok, my cursor move smoothly on it and all the menus work as fast as it should but if i move the cursor to the desktop if goes slow-mo as well as the start menu the task bar going up and down etc... Reboot solve it.

Another really strange thing is that Fire Strike drop fps's to 20 in Graphics test 2 (I neves saw less that 70 on my monitor) and even crashes. The problem here and what blow my mind is that Heaven Unigine with Directx11, High and 2560x1440 gives me an average of 117 FPS and I cant see any drop.

I havent been testing more games so far, just some WoW and it keeps the usual fps.

 

What I have done:
Clean Windows 10 Pro installation --> Update Windows --> Install MOBO Drivers --> Install AI Suite to control fans --> Install Nvidia drivers --> Update to Geforce Experience 3 --> Install Asus GPU Tweak (touching nothing, just install) --> Install Battle.net --> Install Overwatch --> Install Curse (Voice) --> Optimize Overwatch with GE3 (keeping 2560x1440, it recommends 4K with downscalling) --> Run Overwatch.
And ¿what do you think that happened? Yes...  Problem still there. I installed Steam and 3DMark from it and run 3DMark, again the same problem. Heaven keeps going smoothly.

 

I know this is a challenge but ¿can someone give me some ideas to fix this?
Please....

Thermal throttling perhaps? 

 

Can you check your temperatures please with Speedfan or something and post them while playing Overwatch and idling?

Well, I never had more than 60°C on my CPU running Intel Burn Test and my CPU O.C. passes a 24h Aida64 stress test. My GPU ingame doesn't reach 75°C and that with the stock fan curve, with my personal curve I never saw more than 68°C. Btw in GPU Tweak Monitor I see really unstable GPU usage while this problem happens. And yep GPU Temp goes to 51 aprox. So I really dont think I'm dealing with thermal throttling.

Any other idea, I really would love to solve this issue this weekend.

Can you open up MSI Afterburner monitor while you're playing and than post the graph after playing.

Idk wft just happens but after a new clean windows install it works ok. I haven't installed Curse this time, but drivers, AI Suite, GE3 and Asus GPU Tweak are running with np.

If this shit happens again today I'll try to get an Asus GPU Tweak Monitor app screenshot and maybe Aida64 stats during the game.
