Hello my pc has always worked fine. But suddenly when im browsing, my pc has began to lag and buzz when loading any side. It will buzz and lagg more and more as the time goes. And to the end i need to restart my pc to fix this problem, because it is too annoying.
I have already checked my cpu it goes to 40% max when i loading a side.
I checked the cpu with real temp min temp is 33C and max 46C.
When i have played a game like need for speed rivals in some hours then in the cutscenes the sound gets off in 0.3 sec and i hear a "tik sound". But when i am in game and racing, everything running fine.

How can i fix this?
System spec
CPU: Core I7-2700K
GPU: Gigabyte AMD Radeon 7970 GHz edition
RAM: 4 Sticks. 16 GB Corsair vengeance.
Motherboard: Gigabyte GA-Z77-D3H
PSU: Corsair CX600

Games are installed on my HDD: WD 4 TB black
System and savegames is on SSD: Samsung 500GB 840 series.

Hope you can help me guys. Really thanks if you can help.

Sounds like a psu issue. Ticking a buzzing is a sign of a psu problem. Take a look at it and see if anything seems wrong, try it on another system to see if you get the same results, if it is faulty best to get a new one rarther than risk it harming the rest of your system

I have Bullguard internet security

I did:
Full scan. Nothing
Malwarebytes full scan. Nothing
Rkill. Nothing


And nothing uses the computer. As i know when you have a virus you cpu will be used more.
When i do nothing. The cpu is always on 1%.
