System Specs:
B450 Gaming- F (Switched from B350 Gaming- F just in case it was motherboard issue)
ryzen 3900x (NXZT X62 Kraken AIO)
Trident Z RBG 32GB Ram (2 sticks are 3200mhz, and other 2 are 3000mhz) XMP enabled
MSI Trio 2080 TI
850 evo 500GB SSD
850 watt gold certified PSU( brand new)
I have tried almost every combination, Switched to a brand new PSU, tried stock cooler for CPU (previously used AIO cooler), switched graphics card, and tried booting with one ram stick only. I'm running out of options. I played Left 4 Dead for about an Hour , once I switched to Rainbow Siege it shut off randomly. Sometimes it shuts off without any game running, then it gets stuck on infinite loop.
I'm wondering if I messed up something in the bios.
