fps/gpu/cpu drops

[Jiri]

when i am playing a game(bf4,bf3), after 2 min my fps does drop from 70 to 20. this happened after i installed a new cpu fan. so i checked the tempetures of my cpu and when this fps drop happens my cpu temp is 47C, thats not the problem i think.

then i used afterburner and task manager to determine what the problem is. when the fps drop happens my cpu and gpu load drop is massive. you can see this in the attached file.

so can somebody help me how to solve this problem.

non of my hardware is overclocked

 

specs:

fx 8320

r9 270x

8gb ram

asus m5a78l-m/usb3

 

edit: it also happens  when i use cinebench. and the day i installed the cpu fan this problem didnt occur.

What was the problem?

I reconnected all the connections from the power supply to the motherboard and graphics card. so I think one of the connections wasn't good

did that and i reinstalled the cpu cooler. also i noticed when i removed the cooler that the thermal paste didnt covered the whole cpu, only the middle. so i applied the thermal paste in the 'x method' instead of the 'line method'. the cpu runs a lot cooler now and so far i didnt encountered cpu load drops. fingers crossed that the problem is fixed:)

nope didnt fixed it. problem is still there
