I am having trouble with my machine, after leaving it off for a couple hours the first time it attempts to boot it does not post, turns off and on again then works.
The machine turns off when the dram led lights up, so I tried reseating ram and using other ram sticks altogether but it only made it worse, now occasionally it bootloops and I have to reseat ram multiple times to get it to boot.
Once turned on the computer works flawlessly, no bsods or anything.
Memtest86 shows no issues after 4 passes, I updated bios and changed cmos battery too.
So I think mobo is on the death bed, not sure how to confirm this besides wait until it refuses to turn on regardless of what I do.
As for a replacement, is there a difference between b450 and b550 chipsets? I would like to upgrade cpu in the future but I see both of them already support latest gen ryzen.
As an additional note, I lose display altogether if I plug any usb device that has power in it, say if I plug a printer and it is plugged into power, I lose display, but not if it is not plugged in.
