Question PC crashes after 20 minutes of gaming even tho i have a really good PC!!

[Rushxx00]

So i bought this pc about 6-7 months ago and at first month it was perfect i ran every ultra mode and it was perfect.
after that month my games started experiencing crashes or crashing during loading in!
And so i asked around on the internet and people assumed it was my Ram, but when i took it back to the store i bought it from, after some testing they said it is my CPU!
So they swaped my cpu to a new one and boom it was fixed and everything was fine…
Now after 6 month i am experiencing random crashes in the game mostly after 20 mins with out any crash errors unlike before! I jump in the game everything fine until that 20 mins mark boom it crashes! No error no nothing just crashes and takes me back to the screen…. (Same for 3-4 games )
Everything is up to date and still same problems.

Ty for replying <3….

Welcome to the forums, newcomer!

Intel's 13th and 14th Gen processors have been riddled with issues, the stop gap was a BIOS update or an RMA of the CPU if the aforementioned BIOS update didn't help resolve the issue.

My pc specs:
When posting a thread of troubleshooting nature, it's customary to include your full system's specs. Please list the specs to your build like so:
CPU:
CPU cooler:
Motherboard:
Ram:
SSD/HDD:
GPU:
PSU:
Chassis:
OS:
Monitor:
include the age of the PSU apart from it's make and model. BIOS version for your motherboard at this moment of time.

What games are we talking bout here?

Just an FYI, the sweet spot to any DDR5 platform is DDR5-6000MHz. To add, running X.M.P was what exaggerated the instability issues seen on 13th and 14th Gen platform, so DDR5-7000MHz is possible on paper but I think that's what's exacerbating the issue. A stop gap to that issue was to downclock the ram's frequency to reduce stress on the Integrated Memory Controller. Try and downclock the ram to DDR5-6000MHz and see if that brings stability to your platform.

hey there man ty for your response <3

games (indiana jones , red dead R 2 , hell let lose , Hogwarts legacy ) all same issue closes after 20-30 mins

also my rams are 4 pieces of 8gbs ram and with out the XMP Profile on default it is 4400 MHz but with the Ai overclock tuner on XMP1 it is 5200 MHz , the problem is that i was running that for 3-4 months and there was no problems with it i was averaging above 200 fps every game !! so i wonder why would that be the problem now !
