LOW FPS In Games And CPU and Memory Peak VERY High

[MrMarley]

Hi there.

Recently upgraded my PC to a Intel Core i5 4690k and a MSI B85-G43.

Everything was running fine getting great FPS my windows was running very slow even though i reset to factory settings.

So about 3 days later i started to play DayZ Standalone with my friend and i had gone from 60 FPS to 13? to i went into task manager and looked at my CPU usage and it was very high around 80% and so was my Memory Usage about 6.50GB.

I have no clue why this is happening and extremely upset spending £300 on a new rig and it not working to my expectation.

Does anyone have a idea into why my cpu is peaking so high and i am getting extremely low FPS in game?

PC Specs:
Intel Core i5 4690K
Nvidia Geforce GTX 760
MSI B85-G43
500GB Hard Drive
BenQ GL2250 LED 1920x1080p
12GB Ballistix Ram
Corsair 750Watts

Please leave a comment and hopefully someone will be able to help me out!

Thanks Alot

Check for overheating

There is no overheating already checked CPU stays around 30-40*C

Check Task Manager, see what process or application is taking up so much memory and loading up the CPU like that.
I suspect the system has picked up a virus, possibly a bitcoin miner so run full system sweeps with Malwarebytes for any malware infections and something like AVG or Avast! for virus infections.
