I recently purchased new computer parts (Mobo, RAM, PSU, CPU) and have been having a computer crash problem ever since obtaining the new products.

I have returned the CPU and MOBO and received new ones and still have the problem. I have tried a different power supply and still have the same problem.

When I'm playing video games(rocket league, CSGO, rust) my computer randomly decides to crash and the only solution that I've been able to figure out is to under clock the CPU.

Any suggestions are more than welcome. I've been attempting to diagnose this problem for the past 3-4 months.

What are your temperatures? It's possible your computer is overheating, and crashing.

CPU temps when I'm monitoring it and looking over while gaming never exceed 55*C

GPU Temps under heavy load cap out around 80*C

Try booting with one stick of RAM installed. Does it still crash?

I've tried each stick of ram individually. Both sticks crash.

 Sorry I should've specified exactly what I did.

re-install windows on the 128gb ssd? or get a cheap 80gb hdd and install windows on that then see if your pc crashes while booted from it

you shouldn't have issues with the psu, but maybe in the off chance it is faulty, put your old one back in and then try that?

It was happening with the old PSU, I bought it because i thought it was initially a power issue(and due for an upgrade to be fair).

Issue still occurs. Only thing that hasn't been replaced is the GPU and the ram is only on its first iteration(which ive done single ram test for both sticks).

Is it possible that the Grahpics card when put under stress can cause the CPU to crash? I've had other GPU's crash and just reboot without causing the whole system to crash.

yes i had a gtx 570 which i was trying to fix that would cause the entire system to crash under load, had a 290 do a similar thing as well but that was when i installed drivers for the gpu, try integrated graphics?
