Hey guys, ever since 6 month ago my PC started to have fps drops in every single game I play among them are: Minecraft, scrolls, battlefield 3, warthunder. I used to max them all especially BF3 and it ran on ultra without issues. I have no idea why that is happening and will gladly hear you guys out.
NOTE: Half a year ago I got a "fixed" GPU after sending it to ASUS but it kept making a rattling noise as fan seem to touch the metal below it. I fixed it by pulling the GPU a bit with a wire. Additionally there is a weird buzzing noise coming out of the pc.
CPU:Intel core i7 2600k
GPU: Asus gtx 570 direct CUII
RAM: 12GB Patriot 1333EL series
Motherboard: Gigabyte GA-Z68XP-UD3
The whole system is almost 4 years old, never changed and always was cleaned off dust.
What part of the PC can cause the FPS drops in every game?
I tried: re-installing windows, changing gpu drivers, cleaning dust.
Thank you for help in advance, Alexander.
