[yoyoiwnl]

so i built my second pc about 1 year ago and around march this year some games where crashing and its been getting worse and worse and now every time i play fortnite or red dead 2 it crashes 30 mins to 1 hr anyways i kept getting a gpu error when it crashed so i thought it was my gpu so i did a rma and i still get the crashes so then i thought its the power supply so i got a new psu today "be quiet! Pure Power 11 600W, BN627, 80 Plus Gold, Power Supply" and i still get the crashes any idea what you guys think it is
ALSO after my game crashes my pc freezes every 10 seconds then comes back 1 second later
(update) i reinstalled windows twice i use ddu and i did prime95 and furmark for 1hr and noo crash im super confused and lost.

Are you overclocking anything (CPU, GPU, memory)?

What are your CPU and GPU operating temperatures at idle and under load?

What speed is your memory rated for and what speed is it set to in your BIOS?

so my cpu on prime 95 stayed around 57c and never went over
my gpu on furmark reached 79c but stayed around 78c
no overclocking
my ram is rated at 2400MHz
on my bios its rated as 2405.47mhz
