I made a gaming pc for a friend, now it's laggy and the fps are bad.

What happened was, I built a brand new high end, high budget gaming pc.
It worked really well, performed like it should and all, just like any brand new gaming computer should.
Then all out of a sudden, it started acting up. It went from 60+ fps in Arma 3 to about 3 - 10fps, which is abnormal and weird. Something really slowed down the computer, we are in the process of trying out different "solutions" like changing power sockets.

Anyways. Speccy link: https://goo.gl/dGeRkg

Specs from dealer was:

Cpu: i7-7700k Kaby lake 4.2GHz (non overclocked)
MB: Asus Rog Strix Z270E
RAM: Corsair Venegance DDR4 (32gb)
PSU: Corsair HX750i
SSD: Samsung 960 Pro 512GB M.2 PCIe
HDD: WD Desktop Black 4TB
GPU: Zotac GeForce GTX 1080 Ti Amp Extreme (Supposedly 11GB of vram, even though Speccy said 3gb lol)
Windows 10 Pro.

Yeah that is pretty good for temps under full load.

Have you tried any of the basics like removing all drivers with DDU and installing fresh ones?

I've also seen bad PSU's cause this issue. You seem to have a decent once but if it is having issues. It could lead to such problems.

If you are plugged to a power strip or anything. I would try to bypass it and in Windows turn on high Performance mode. See if that makes a difference.

The system temps remain pretty cool, close to what Speccy is reporting, except for the gpu, which rised to 40 - 60 when in use.
Nothings been overclocked on the computer yet.
 


Wait so cpu temps don't go towards the 80c when under load?

They go to about 40 - 60 degrees, depending on the task.
I've installed a pretty decent cooler for the cpu.
