[SOLVED] PC behaving stragely after windows update!

[Deleted member 2849646]

I have a dual monitor setup and after doing all the windows updates on a fresh windows 10 install inc optional installs inc chipset drivers etc, when I rebooted one of the monitors it stuck at 640x480. One is at 1920x1080. No matter what I try I can't get the second monitor to 1920x1080 again. I've done a fresh windows install twice but the same thing happens! I've changed the cable and it still happens.

Also, when I reinstall windows, whilst the system is booting up both monitors (Dell logos) have the same resolution. Also resolution is same just as windows is 'getting ready' (mirrored screens). However as soon as windows has finished installing and is on desktop, one of the monitors is 640x480 and I can't change it. When I go to display settings for the monitor, it's not detecting it as a dell monitor. It just says: "Display 1: Wired Display" instead of the model and make of actua monitor.

I'm pulling my hair out trying to fix this! Anyone have any suggestions what's going on and how to fix this please?

Thanks.

Chipset drivers aren't optional, they're essential for the platform to operate optimally.

Mind sharing the specs to your build?
CPU:
Motherboard:
Ram:
SSD/HDD:
PU:
PSU:
Chassis:
OS: version of Windows 10
Monitors:

Do include the age of the PSU alongside the make and model of your PSU. Speaking of Windows 10, where did you source the installer for your OS? You're advised to manually source the drivers for your platform from manufacturer's support site. You can get the majority of the drivers from the motherboard's support page, while GPU drivers(if discrete) can be found on Nvidia/AMD's support site.

It would also help us two fold if we knew the BIOS version for your motherboard at the time of writing.

It’s a bog standard dell optiplex 3040 sff. No idea on the other questions. I created a windows 10 installation usb from windows website. I had ethernet plugged in during install. Does this cause issues? Does windows auto look for drivers during first install (from internet).

Also, does this sound like a bios/mobo software issue, or is it a windows os issue? Can’t figure it out!

If you created the installer for Windows 10 using Windows Media Creation Tools, then you should be on version 21H1. As for the question on BIOS, Windows 10 and the BIOS are tied in the sense that if there's something that the OS or the BIOS don't like, they won't cooperate, which often leads to a black screen or glitches of sorts. Now that I know you're on a prebuilt system, you should use the Service Tag on your OptiPlex keyed into Dell's support site to source a list of drivers meant for your platform. Once you've manually download all the latest drivers that are relevant to your platform, you can proceed to (re)install them manually in an elevated command, i.e, Right click installer>Run as Administrator.

As for the Ethernet being plugged in, it's best if you install the OS without internet connectivity, once installed, manually install all relevant drivers, then reconnect to the internet and then let the OS update itself. No SFF discrete GPU, correct?

Windows/BIOS/drivers issue, to me.
