FPS drops in games only.

Hello there. There's a problem with my computer (I'm assuming) that whenever I play games, even from 1998, I get very large FPS drops. Everything's fine for a couple of minutes, but then it drops to about a quarter of the frames that I had, then it goes back to normal after a couple of seconds. A few months ago I took the PC to a mechanic, and they said that everything was fine, nothing strange showed up. When I brought it back home, I tried running MSI Kombustor, did a few tests there, but the FPS didn't drop. Same with 3DMark. On the sky diver test, framerate would mostly stay at 60-80 (Where if I was playing a game, and let's say it would run on 60, it would drop to 15-20 for a couple of seconds.) I will be uploading a few videos which show this happening.

I have tried:
Turning off "Cool n' Quiet",
Unparking CPU cores,
Switching monitors,
Playing those same games on Linux or different versions of Windows (7,10,Fedora.),
Playing games COMPLETELY offline (which means turning off the modem and disconnecting it from my PC),
Lowering the settings all the way,
Switching APIs from DirectX to Vulkan (DOOM),
Disabling anything that is not required to play.
Updating to last drivers from AMD.

My specs:
Windows 7 Ultimate 64-bit SP1
AMD FX-6300
8GB of RAM
ASRock 960GM-VGS3 FX (CPUSocket) (motherboard)
Philips 227E4LH (1920x1080@60Hz)
2048MB ATI AMD Radeon R9 200 Series (R9 270X)
931GB TOSHIBA DT01ACA100 ATA Device (SATA) (Hard Drive)
Qualcomm Atheros AR8151 PCI-E Gigabit Ethernet Controller (NDIS 6.20)

P.S Don't know if this is gonna be any use, but when I played PUBG and this problem kept happening, sometimes the game said it had connection issues.

Example of this:

Didn't help. Installed latest drivers from AMD's site.

Looking for an answer to this kind of issue myself. After checking drivers/temps, checked hard drives for any issues, used ccleaner, checked for malware and viruses, and closed any other applications that could've been the issue, the only two things I could look at were either that my gpu is failing, or psu is failing. If you do my checklist and nothing works, these two are the only things I cant think of. When I made the same post, the only things people said were temps, drivers, or gpu sucks even though I had said I checked for those very things. Depending on how old your system is, it could very well be something is failing but do my checklist first.
