Windows 11 update bricked my motherboard

I was doing a windows 11 update and after about 20 minutes of black screen I reset my computer Which I realized was a mistake now I have tried Resetting simos I then proceeded to Do a bios Flash with USB it took several hours of the flashing red light I cannot even turn on my computer when I press the power button my screen picks up a signal for a second or 2 and goes blue from sleep mode then write back to sleep The motherboard Status lights all all illuminate in order and then turn off as if nothing's wrong and it has booted I have tried everything to get into Bios I tried to use different inputs with Motherboard outputs and also GPU outputs. I only get a split 2nd signal When the power buttons pushed I even tried control alternately I tried to remove the battery and then short it I tried putting putting in new ram I tried putting in new SSD that was empty and tried to reinstall windows nothing is working please help

You wanna say CMOS not simos or dolores..... you brick your mobo not windows fault....

I'm no expert on what has happened, but I think that whatever went wrong with the 'Windows' update 'is what it is'. I'm pretty sure resetting the BIOS, flashing the BIOS, removing the CMOS backup battery... replacing the RAM and SSD is a recipe for disaster.

The 'dead' PC in the state where the update crashed should have been bootable back to the BIOS if you did a forced or hard reset.

I'm sorry it's not better news and the above isn't meant to be too critical. Hope you can sort this.

Welcome to the forum. I'm sorry you've managed to get yourself into such a pickle. As others have pointed out, unless the windows update you applied happened to be a bios update, windows update is not the culprit here. There was no cause to flash your bios in this situation or to work inside your case at all. I suggest your contact MSI support to see if they can help you recover. At the very least, I feel sure you can return the motherboard to MSI for repair and they can replace your bios chip if necessary. Do not attempt to do this yourself.

Don't beat yourself up too much about your error but consider it a lesson learned. We've all screwed up at one time or another. Good luck.

I would check the power supply unit.

As to the power, ANYTIME one wants to change or add a plug-in item such as a memory module or video card, etc., it is necessary to remove all power first. The motherboard always has |power whenever plugged in, the On|Off switch attaches to it and when pressed wakes things up. Not removing power first can cause damage that will require a new motherboard. The capacitors on the board retain power so pressing the On|Off switch helps drain off residual power.

Disconnect the power cord from the power supply and press 5-6 times the power button to completely discharge any capacitors. Then connect the power cord again and press the power button to see if it switches on. If it switches on at a black screen try to reset BIOS by putting the jumper at the clear CMOS pins. I would also remove the battery for 1-3 minutes to make sure it loses all settings. If these don't work your motherboard may have died or your graphics card, ask professional service. This is not related to Windows Update, is a hardware issue.

I guarantee you this after upgrading from windows 10 to 11 last week it bricked my motherboard which was MSI as well i contacted them they say its nothing to do with their hardware. My pc was running compltely fine no overclocks nothing smooth as a whistle. I also see lots of people on youtube stating its windows 11 .

What do you mean? If you cannot even see the booting screen or enter BIOS, then it is a hardware issue. If it is a software issue you should at least see the Windows loading screen and get stuck there. Recently a friend of mine had a bad RAM module and his computer wouldn't boot. If you have more than one RAM modules, try them one-by-one. If lucky, your motherboard and CPU are OK and you should only replace the bad RAM module. Also try another power supply.

It's an old post, Dec 1, 2022.

Without the KB number it's hard to tell which update did it. I have 3 Notebooks [2 bought new 1 given for parts] and 2 Desktops [1 bought new and 1 given for parts] and am not seeing any issues.

It's definitely not a Windows issue, as long as he cannot see any image on screen, not even the BIOS splash or Windows booting logo.
