I'm running:
MSi B550M Pro VDH WiFi
AMD Ryzen 5 5600X
GPU Gigabyte Gforce GT1030
A750FG PSU
I flashed the latest BIOS and set to UEFI. Later on today, the system started to reboot on a very frequent basis. As I started installing Windows, it rebooted continually so it too aged to finish the install. NOw, every time I log into Windows it reboots..
If I leave the pc at the windows splash screen (the one from that beach in Portland) it doesn't reboot for up to 5 mins. But when I log in it reboots immediately...
Thanks
John
