Mouse Stutter / Screen Flicker Issue

[Splashman777]

So here are my desktop specs (upgraded ASUS prebuilt over the years):

• i3-4170
• GTX 1050ti
• 500W Power Supply
• 250GB SSD
• 1TB HDD
• 35" 1440p ultra wide monitor 

I have been running into issues with my mouse occasionally stuttering while I drag it from side to side and my screen flashes black for 2 seconds sometimes, especially when I bump my desk. It is not the mouse or USB ports that are the issue, I've tested multiple of each. I bought the 1050ti a year or two ago refurbished but it works great except I am starting to suspect there is a CPU bottleneck that could be causing these issues. I took out the GPU to see if the issues disappeared and they did (expect the graphics were garbage because of the old iGPU). 

 

Does this sound like a bottleneck to you guys or just signs of a dying GPU?

If it is a CPU bottleneck, what would be the cheapest way to improve it? Should I just buy a new Ryzen motherboard / CPU combo?

 

Thanks!

I would first try DDU. if the mouse is skipping and you are getting black screens, its pretty probable its a driver issue. re-install it with DDU and that might fox your problem.

I'll check it out. After I uninstall should I just re download the latest Geforce drivers?

DDU will completely remove the nvidia drivers. So yes, you will need to download them again yourself.

That might have fixed it!!! Also, changing my refresh rate fromm 100 to 60Hz may have stopped the screen flashing. Thanks!
