Not able to turn it on at all my motherboard lights up then turns off instantly when i turn on the psu so I'm trying to figure out what's wrong since nothing is plugged in wrong I'm hoping everything is fine but i probably did something wrongYour system should be able to boot with only an m.2 SSD installed. However, you still need to have an operating system installed to do anything with the PC.
Are you able to access your BIOS?
