Question PC rebooting and games crashing

[geomilios]

Hello guys,

I recently built a PC and I had problems with random reboots using windows 11 and a most possible faulty power strip. I went to a store in order to give my PC and fix it and they fresh installed windows 10 and downloaded all the latest drivers. They told me that my PC was working just fine so I took it back to my place. I just downloaded GTA V and It takes two and when trying running them the game either crashes without any warning or error message, or the PC reboots. I ran FurMark to test my GPU and the PC restarted after 8-9 minutes of stressing with normal temperatures (~ 65-68 degrees Celsius). Other PC components run at normal temperatues too. What could cause all these?


PC Specs:

CPU: AMD Ryzen 7 7700x
GPU: Gigabyte GeForce RTX 3060 12GB GDDR6 Gaming OC rev. 2.0
Motherboard: MSI Pro B650-S WIFI
RAM: Corsair Vengeance 2x16 DDR5 5200MHz
SSD: Western Digital SN770 SSD 1TB M.2 NVMe PCI Express 4.0
CPU Fan: Arctic Freezer 36
PSU: Seasonic G12 GC 750W 80 Plus Gold
Case: Kolink Observatory HF Mesh

Hi
Did you Thermal paste when installing the Arctic Freezer 36?

geomillos Hello. PC rebooting issues are caused by one of the following: (1) heat (2) software (3) hardware. In your case, your Windows 11 installation was removed and Windows 10 was installed, so that eliminates (2) software, in my mind. (1) If the issue was heat, then that would mean that your CPU met and exceeded TJ Maxx. I'm not sure what that temperature is for a Ryzen 7 7700X. When you installed the Arctic single tower air cooler, did you remove the plastic protective cover from the plate? If you did, and if the fan is properly spinning, then I seriously doubt that the CPU temperature could get high enough to reboot the system. By my process of elimination, that leaves (3) hardware. According to your motherboard manual, your two RAM chips should be installed in slots A2 and B2; please verify that. Also, what BIOS version/date are you on? Lastly, assuming those conditions are verified okay, then my assumption is that your power supply, even though new, maybe the culprit.

Keep in mind, that this is only based on my opinion.
