Question Monitor Not Detected After Bios Update

[ssmanman]

I have an old gaming pc that desperately needed and upgrade. I have a ASUS prime 450M motherboard, and was going to upgrade my Ryzen 5 2600 to a Ryzen 5 5600X. After the install, I had no monitor input, which I learned (or thought) was due to my bios version being very old. I put my old cpu in to download the most recent update, in which I did, it stated I needed a system reset, in which I did, and have had no monitor detection since. I tried taking out the lithium battery, with the same result. What can I do?

Are you saying that you cant even get into bios now, no onscreen post at all?

Also, have you tried plugging the monitor cable into a different port, tried a different cable? ( what type of cable connection?
Have you tried a different monitor?

I have tried 2 monitors, and they are both hdmi.

When I turn my pc on, there is no detection from my monitors.

A cmos reset from battery removal still didn't fix it. Does the motherboard have an onboard graphics chip?

It does not have one.

It does not have one.

have you changed the cpu out for the new one?.

once you update the bios the 2600 wont be detected anymore.

theres a very limited amount of space on the b450 chipset so it will not boot most likely now until you install the 5600x

older boards of the b450 and lower had 16mb bios chip. because newer chips came out they have to make space by deleting older cpus from the list of support on newer bios.

newer ones later got a 32mb overhaul.

I’ve tried both of the cpus, and neither work.

1 stick of ram seems to be working. Why is that?

1 stick of ram seems to be working. Why is that?

which slots where the ram in

ram to work in duel channel must be in slots 2 and 4

possibility is 1.

motherboard has failed ram channel.

possibility 2 ram failure. you can test if its ram by removing the stick thats working with pc off and trying to boot the other stick in slot 2 instead. if it fails to post its a bad ram stick.

some motherboards wont post if there's a bad ram stick installed.


mixed ram if you have 2 diffrent types of ram this can cause the system to fail if it wasnt bought in a kit.

sometimes it works for a while then just fails.
