Bottlenecking / CPU Help

[LynxPlays]

Hey,

 

So I've been trying to work out what the problem has been with my PC for nearly a year now, but I've been to lazy to get the bottom of it.

The problem is that about 4 months ago i suspected that my CPU was dying and i needed to get a new one, however since running more and more benchmark tests on Cinebench I've come to the conclusion that something is bringing my whole setup down to where i can't run demanding games on 200+ fps anymore, nowadays i get around 50 with medium settings.

Some people have told me that it was the power supply that might be dying, and some suggested that it was the CPU - but i feel like my CPU would not be bottle necking my GPU that badly.

Here are my specs:

 

- GTX EVGA 1080 ti

- Intel i5 8500 3.6 GHz

- 16 GB Ram

 

Another thing that I've also been noticing is that my CPU has been running at a constant 100% in the task manager even when i am not gaming, and when i am watching a video and gaming at the same time, my pc may sometimes (very rarely) just shut off. I am willing to provide any other information and can open up my PC to inspect parts if needed, but i really need help on this as its something that has been getting progressively worse. And if push comes to shove, would it be worth sending the PC to a specialist to have a look at??

Thanks alot.

so are your PCU scores way too low?

I haven't actually tested my PCU in terms of bench marking, if you could link me a program where i could test them all individually i could send you all the results back.

Yeah, what process is using all that CPU? It can be a virus, have you scanned with a decent anti virus?

I have Norton and i run frequent checks to test for viruses
