Bios update successful and then pc froze in Windows and after restart won't boot

[Sparxycat]

Hi all,

I updated my bios on my Asus Rog dark hero and all was well. It updated, restarted and loaded back up fine. Then after a while everything froze and I restarted the machine. Now when I try to boot it up I get power going through but get the DRAM Led and CF on the readout and it then restarts and tries again.

I’ve tried reseating the ram and also just using one stick and swapping the stick out to no avail. I can’t work out what has gone wrong.

Pc spec wise I have the motherboard above and 4 sticks of Corsair dominator platinum RGB DDR4 3400, a Ryzen 9 5950x and an EVGA RTX 3090 for help. Just don’t seem to be able to get it to boot. Used to build pcs back in the day but dropped out of the scene and now I’m well behind so my skills are minimal!

Welcome to PCHF,

What PSU do you have, if it is modular, check that all of your connections are secure at both ends.

What happens if you restart the PC and access the BIOS, will the computer stay in the BIOS for as long as you leave it there or does the PC still restart.

I have a Corsair rm1000i PSU that is modular. All cables are nice and secure at both ends.

The computer doesn’t actually make it into BIOS anymore. It tries to boot, all the RGB starts to fire up and the fans start to spin up and the mobo LED for DRAM lights up and then the machine restarts and tries the cycle again and again.

Sorry to say but the BIOS may be hosed

The below is canned info so you will be aware of most if not all of it but others may not be;

The following checks require the computer case to be opened so take the following safety precautions 1st, disconnect the power cord from the wall socket, [COLOR=rgb(226, 80, 65)]press the case power button for twenty seconds or so to get rid of any residual charge in the system, take anti static precautions before touching anything inside, you can do this by touching a bare metal part of the case or PSU or if a notebook by touching a household radiator or associated copper feed pipe.

Remove the CMOS battery.

Disconnect everything from the MB except the 24-pin EATX Power connector and the 8-pin ATX 12V Power connector

Remove all the RAM.

Remove the GPU.

Press the case power button for twenty seconds or so again to be sure that there is no residual charge in the system

Insert just the one stick of RAM in the second slot away from the CPU (Slot B2)

Make sure that the CPU cooling fan is connected to the correct header on the MB.

Put the CMOS battery back in.

Connect the keyboard and the mains power cord.

Press the power on button to see if the system powers up and stays running, aware there will be no video and are just checking to see if the PC stays running for now.[/COLOR]

Sadly I think that may be too much for me especially as I’ve only had the pc 3 months. I’ve contacted the company that made the system and they are going to take it back in and look at it for me.

Frustrating that I followed the BIOS update using the Asus AI suite and did everything they said and the bios update even said it succeeded and that may still be the issue.

Thanks for your time, I hoped it could be something simple for me to fix but hey.

The steps provided are only basic and being honest I`m not sure of anything that could have been suggested that would not involve going inside the computer, you have done as much already by moving the RAM around.

All we can do then is wish you good luck.
