Hey,
so, as the title suggests my PC crashes at random after 2 years of use. Now bear in mind nothing is overclocked and I have tried to be conserving of power. My specs are:
Intel Core i5 - 4690;
R9 390 (8GB edition);
some ASRock motherboard I forgot;
some random 750W CM PSU;
8GB 1600 mhz DDR3 RAM (corsair stuff)

Before, it started as random cut offs, my screen went black for a few seconds and then said something along the lines of "display driver has stopped working". These happened once each time I booted. So crashes happened randomly about 3 weeks ago, twice a week or so. Last night, a crash happened when I was just browsing stuff. And today I experienced 4 of the same nature while playing LoL.

The way a crash goes is basically my PC powering off, no weird glitchy sound, no slow-downs, just my PC suddenly powering off. I've tried updating GPU drivers, and it didn't help. What I've concluded is that I may have a dying GPU, which is highly improbable since I've had a dying GPU and I know how one acts like.

Event Log: Event ID: 41, source: Kernel - Power (so basically any crash ever).

Apart form that I've experienced 2 BSODs.

If anyone has any idea what's going on I'd be deeply grateful.

How to know whether it's overheating? And how can a PSU overheat on basic tasks like browsing online and light games like LoL when it hasn't done this on GTA V or The Witcher 3 on Ultra?

Doesn't seem to be the GPU it's constantly on 41-42 degrees, it can be the PSU so what to do about an overheating PSU?

If it can't get air, it can't power you system regardless.

Is the PSU fan facing into the case or out of it? Does it have room to breathe?

is the corsair AX 760W good?
 

Yes. It is a tier one PSU on the list I linked to.
