something overheats and i don't know what

[Rudmer15]

Something in my PC overheats and i don't know why. These are my specs:
CPU: AMD FX-6300 (not oc)
Motherboard: ASRock 970M Pro 3
GPU: Asus Radeon RX 460 STRIX
RAM: Kingston HyperX Fury black 8GB
PSU: LC-Power LC6460GP3
CPU Cooler: Cooler Master Hyper 212 EVO
HDD: Seagate HDD 1TB

Every time when i play a game my pc freezes/crashes so i have to force-press it out. It's a kind of freezing i've never read about before. so what happens is that my screen changes to a color of what was happening while playing. Let's say i was looking at dark-green grass when it crashes. I then see over my whole screen that dark-green color. Sometimes when i was skyping while playing i could still hear my mates talking for 2-3 secs before it turned into distorted noise. About the overheating, i already did some stress-testing. I did my CPU (with Aida64) , and it crashed after 13 mins. But the temp didn't go higher than 48. So i stress tested my GPU with furmark and nothing happened. I play a lot of overwatch but i have to play at the lowest setting (it'll crash if i play on higher settings) . I'm also forced to have my side-panel of. It will crash after 15 mins of playing if i don't. My friend told me my PSU could be the cause because of its low quality. But i don't know if that's an explanation for overheating. Thank you in advance.

A good tool that I use to monitor temperatures is Speccy. With speccy running try Prime95 to rule out CPU, then try Furmark to rule out GPU. If they are fine individually, run Prime95 and Furmark at the same time. Keep an eye on the temps in Speccy.

I downloaded and opened prime95, i have 4 options: Small FFTs, In-place large FFTs, blend and custom, which on should i choose?

It could be the PSU or the motherboards VRM is overheating thus downclocking the CPU and eventually crashing. Your board does have heatsinks above the VRM but it could still overheat. Make sure that you have good airflow inside your case. You should have one fan in the front sucking air in and another in the back sucking air out. As for the PSU, you should test your system with another unit in order to know whether your current PSU is working properly or not.

I always run Blend.

My friend (who knows more about PC's than me) said i have really good airflow and i've already tried another PSU, but it was of the same brand and only 40 watt more.

Since you are forced to open the side panel it seems that the current airflow inside your case in not enough or you have a hardware malfunction somewhere in your motherboard. You probably need a new fan blowing air over the motherboard's VRM. If the side panel of your case has a fan mount, use it. Just make sure that you install that fan as an intake so it sucks cold air inside your case. If you do it, you'll definitely increase the stability of your system. Keep in mind that there is also the possibility that your motherboard somehow got damaged, and if that's the case the overheating issues will get worse by time and the above fix will only work for a short amount of time.
