Windows update that caused my pc to not boot

Question

I was on my computer when I realized it was running slow so I decided to check for an update for windows 10 surely there was, I installed it then after the restart-it developed a post issue where it now sits with power to the system and rgb but the monitor and peripherals don’t turn on or flash. I also was in csm boot mode when the windows update installed. What could have been the issue? Or was the csm my issue? If it is how do I resolve it?

Hi

1.CSM is something that allows booting in legacy BIOS mode on UEFI systems.
The explaination in the Wikipedia is:
The Compatibility Support Module (CSM) is a component of the UEFI firmware that provides legacy BIOS compatibility by emulating a BIOS environment, allowing legacy operating systems and some option ROMs that do not support UEFI to still be used.

So if your PC is fairly new and came with Windows pre-installed, CSM would've been disabled by default.
You don't need to enable it. It's only needed if you must install an older OS that doesn't support UEFI.

2.To help solve your problem, we could power ON your computer and as Windows / manufacturer's Logo appears, Power OFF - Repeat 3 times
Then your computer will go into advanced recovery environment.
Advanced Options > Troubleshoot > Advanced Options > Startup Settings > Restart
Press 4 or F4 to enable Safe Mode (5 or F5 to enable Safe Mode with Networking)
Log in once Windows starts in safe mode
See whether you are able to login. If yes, come out of this and start normally.

If the above advice failed, booting through a bootable USB drive is another method.
