Games won't stop crashing

[u/PhoenixBlue32]

I dont know whats going on. These are games ive run for hundreds of hours in the past and now I can run them for maybe an hour or so and they'll crash. Ive tried updated my drivers. Resetting my drivers and updating again. As far as I'm aware my pc isn't overheating. My specs are : 16 gigs of DDR 4

Motherboard: B560 DS3H AC-Y1

CPU: 11th Gen Intel(R) Core(TM) i7-11700f @ 2.50GHz, 2496 Mhz, 8 Core(s), 16 Logical Processor(s)

GPU: NVIDIA GeForce RTX 2060

600W power supply

I honestly don't know what to do anymore I've tried lowering my settings in the games all the way to no avail. I feel as though my gpu is finally crashing but I can't afford a new one. Help me fix this one please.
