This is my system:

CPU- AMD Ryzen 7 3700x
MOBO- B450 tomahawk max
PSU- 850W 80+ gold
RAM- 32gb 3200 mhz cl 16 ddr4
GPU-: RTX 3080 fe driver:456.71

My problem is that my computer crashes when running Apex Legends or Csgo. It can run games such as Horizon Zero Dawn, No Man's Sky, Code Vein, Minecraft with shaders/mods, and league just fine. However, with Apex legends with absolutely anything other than the stock settings of the card, it crashes. I can't increase even the power limit. For csgo, I played it and crashed. I opened it again and turned every graphic that could possibly strain the GPU on/at its highest. Hasn't crashed on me so far. To note though, the crashing for the two was different. For Apex it shut down the entire computer whereas with csgo the GPU just sopped sending out a display. For the motherboard it has its own inherent OC for 600mhz which I have turned on however, I have benchmarked it multiple times with cinebench, and it runs fine in other games. Sorry for it being so long, but I just wanted to give all the info possible.
