So I've had this PC for almost a year, and everything was going fine till 2 days ago one night i was randomly on my PC and an error occurred, showing that blue screen. After this incident, some things changed. My gpu temperature would go very high even though it's usage was below 10% while the temperature was 90-100 degrees Celsius. And keep in mind this was without playing any game, just Google Chrome loaded up, nothing else. I searched for some solutions, installed the latest gpu drivers from GeForce experience, reinstalled the gpu drivers today. There isn't any background program or anything causing problems as I checked in task manager. This problems gotten so bad that today, while using my PC, my Monitor went into standby mode because of the gpu temperature, which reached 101 degrees.


Here are my PC specs:
Asus rtx 4090
I9 13900kf
4 tb ssd
36tb hd
Asus prime z690
64gb ram
Phanteks nv7 casing

Monitor : Samsung g8 odyssey
OS: Windows 11

Thanks in advance.

Are you looking at gpu hot spot? The limit on the 4090's gpu core is 88C. I believe hot spot is up to 110C.

Someone's gonna need to put some fresh paste on that gpu die.


Since you have a 13th gen i9, the crash could be related to the recent news of 13 and 14 gen Raptor Lake cpus; defects/oxidation/too aggressive boosts/voltage... there's no solid culprit at this time.
If you haven't updated the bios lately, you should at least do that, as board vendors have been releasing updates that force the defaults to run to Intel spec; for the longest time, most Z boards' defaults have been overclocks.
There's supposed to be a fix coming next month: https://forums.tomshardware.com/thr...-root-cause-fix-coming-by-mid-august.3850099/

I have a temperature recorder in my PC, two of them. One for the gpu and one for the cpu. One thing that's weird is that in task manager, it would display my gpu temperature as 100 degrees while the temp recorder in my PC displayed 45 degrees. I've been trying to boot into bios lately but I can't. I used the windows startup option in settings but for some reason it never works. When I tried to do it manually (restarting and pressing f2/del) it wouldn't work as the Asus startup menu doesn't appear anymore and I know for a fact that f2/del r the only keys used to get into bios as it states on the asus startup menu.

Use hwinfo. Task manager is unreliable for that.

Thermal Limit
Max: 88.0°C
Hot spot has a higher temperature range than the core does. If the core really is 90C+, it will force the PC to shut off.

Try taking the cpu out and putting it back in. The board should behave as if a new cpu has been installed and prompt you to go into bios to change any settings.
If not that, you may need to try another cpu in there.
