Hey there,
I had bought all these computer parts new.
Im having an issue where when I start the system, all fans, leds, and everything is working, although I’m not getting any display and then after 20 seconds the pc boots again.
ive tried:
Resetting cmos
Checking each dim slot with a single piece of ram
Reseating CPU
Taking each part out individually and testing
(Which leads to the same boot loop)
I’m starting to think that I had just gotten a faulty motherboard
My specs are
Ryzen 3600x
B450m steel legend
Rx 580
16 GB DDDR4 3600 MHz
1 TB HHD
650 Watt PSU
Someone please help 🙁(
