Remove your RAM and put it back and see if that helps. if not, put just one RAM back and see if it works (try with either of the RAM sticks) and ses if you can find the faulty stick by using some basic logic there.

Also, does your CPU overheat during gaming? Can you check the temps and tell me?

Last question is, how old is your PSU and what's the model of it?

I have tried to change the ram sticks and that didnt work. My highest cpu temp when playing is 65-70 celsius. And my PSU is a 5 year old XION Xon-700p12n 700w Max ATX.

Upon further investigation, you PSU is probably to blame here.

The PSU is not from a highly reputable brand, at least not so much to hand over your expensive components to that crappy one. It does say 700W, but a good 700W PSU (lets say, from corsair) is far more expensive than the price of yours. And with cheap stuff, the components are cheaped out too. 5 years of use and its a pity it even lasted this long.

Swap out your PSU to a better one and test it out. I'm pretty much sure the PSU is failing. And go for a much reputable brand this time, if you want your components to live longer and for less troubles.
