FPS Drops in games

[stormforce]

Hello,
I have one problem. I don't know why but whenever I play any game I get this FPS drops like crazy. Let's say I play Counter Strike Source and at first copule of minutes it sits at around 300 fps. Then after some minutes it drops to 40-50-60 fps for some seconds and then it gets back to 300. That is happening every few minutes.
I don't know what is causing this. I have good PC. Its like 5-6 months old. Here are my specs:

CPU: AMD FX-8350 4 GHz
GPU: AMD Radeon HD 7950
RAM: 8 GB
MOBO: MSI-970A-G43 (i think)
also SSD

What I think it is, is that I have box (stock) cooler on my CPU. Maybe CPU gets hot, and then cooler can't get it down because it isnt really good, so I get those drops.
I dont know... What do you think?

check your temps

I've seen this before, something is throttling due to temperature. Start with the CPU, but it could be the GPU as well.

If you find one of them is getting hot, give the heatsink a cleaning. Hit it with compressed air, but don't let the fan(s) spin, it could damage the fan.

could be dust caked on the heatsinks, causing over heating and throttling or could be a virus. blow the dust out of your case and run antimalwarebytes

check your temps

At idle its about 20c, and in game around 60-70

In core temp app its 20 min and 72 max after few minuts in game.

I ran malwarebyts and its clean. I will clean my case tomorow and tell you resaults.

also, maybe try to update and do a clean install of the latest video drivers. run display driver uninstaller to uninstall the amd drivers

I has this exact problem with a biostar board. Tried everything you could think of and changing the motherboard was the only thing that helped. I tried every different version of drivers and re installed windows, new power supy and video card,(it was time for an upgrade anyways). Only changing the board helped

Hmm, I don't know about that, because it's new PC. And I didn't put all parts together, its made in the shop I brought it from. So I guess they know what they are putting together.

I think I got it fixed. I cleand the PC from the inside, but I don't think that helpt much. What I did is turned off some shit in AMD Over Drive, like Turbo Core and some more things.
