Why is my laptop "randomly" rebooting after fresh install of Windows 11 Pro?

I'd like to get some tips on identify what is causing my laptop to reboot randomly and multiple times per day. Acer Nitro AN515-57 i7 11800H 3060M 16GB 1TB NVMe Windows 11 Pro I tried looking into event viewer but I can't tell what exactly is. chkdsk no error sfc /scannow fixed these C:\Windows\System32\drivers\BthA2dp.sys C:\Windows\System32\drivers\BthHfEnum.sys C:\Windows\System32\drivers\bthmodem.sys DISM repair successful Drivers are up to date with SDIO did all latest win updates. CPU is under-volted but reboots also happen when CPU running normally.
