Low FPS in EVERYTHING (Windows, 3Ds Max etc)

C86G

Hi guys.

I got a problem I really can´t solve by myself + with Google.
Almost everything visual on my computer lags as hell/ has low fps. Moving a window lags extremely, like only every nth frame is shown of the movement.
The same with moving/ rotating objects in Max. I only see every nth frame of it. Like you are playing  a racing game with 10 fps.
 I recently switched from a Nvidia GTX 660 to a 770 but I had the problems with the 660, too. And yes, I did get the latest drivers. Didn´t help. I let Windows update the drivers automatically, didn´t help.

I use
Windows 10
24 GB Ram
GTX 770
two monitors (1920 x 1200 and 1920 x 1080) and each at 60hz.


Please, if you have any idea how to fix this, tell me : /


edit: the task manager window runs perfectly smooth

Have you tried reformatting? If that doesn't work, most likely cause is your hard drive going bad from my experience (has to do with problems reading/writing windows background tasks into memory).

It's also possible to be RAM/VRAM related, but typically if those parts were going bad it would just result in crashes.

Have you tried Task Manager during slowdowns? (Ctrl Alt Del) What does the Performance tab look like?

Task manager says that nothing is wrong.
~5% CPU
~4GB RAM
~2% GPU

The mouse cursor is NOT laggy and some windows that are not directly "windows` windows" like the popup from Nvidia´s installer moves SMOOTHLY. But, and this is the worst, windows itsels and 3Ds Max is laggy as hell.

I use a SSD for Win10 and the major programs and a HDD for files.

No, haven´t tried reformatting. It´s really the last thing I want to do : /

As PolyHertz said that sounds like a hard drive problem, I used to have the same problem when browsing my secondary drive, sudenlly out of nowhere everything became super slow, even programs installed in my SSD. Eventually the drive died and when I got a new drive the slowdowns were gone.

What is the refresh on your monitor set to? Either in software/drivers or on the monitor itself. ohwait, you mention this in your post and your cursor is smooth. Hard drive really doesn't sound like an issue here- just dragging a plain window should be more or less smooth.

With nothing running, what does activity look like on your GPU? Malware that mines cryptocurrency is the New Big Thing or so I hear, might be worth doing a scan.
