PC won't boot into OS after updating program

Recommended Posts

I was using the 20H2 version of Windows 10 when a pop-up on the desktop asked me to update Malwarebytes (I've scanned prior to that, so it isn't a malware).

After updating and restarting, my PC couldn't boot into Windows. I can't get to the BIOS or Recovery Mode because my keyboard only starts working way before the POST.

Also, there is no video output on VGA and a black screen on DVI-D.


System information:

  • CPU: Intel Core i5 2400
  • GPU: Asus Geforce GTX 1050 TI
  • Memory: 8GB DDR3 1333MHz⁽¹⁾
  • Motherboard: iSync CYBH61 LGA1155
  • OS: Windows 10 Pro 20H2

The Premium license key is backed up and reinstated. All user configurations and other data are removed. This process requires a reboot.

Please try to start the system in Safe Mode using the method described under the From a black or blank screen section of this Microsoft support article to try and start the system.  If it works, uninstall Malwarebytes once in Safe Mode then restart and let your system start normally and if the cause of the issue was Malwarebytes the system should be able to start.

Please let us know how it goes.

Hello @stacklysm   I regret your trouble.   Here is hopefully some added tips.  First just make sure that no printer or fax machine, or copier, or other attached peripheral machine is connected to this computer.  If it is a laptop or notebook, be sure it is connected by cord to a power source.  ( i.e. do not rely on battery only ).

If you power off the whole computer, wait about 30 seconds to 1 minute, and power back ON  & let it try to load Windows   ....if it should fail, keep on repeating these ON - Off steps.  After a handful of failures, you should see a actual option to do a recovery.

2nd suggestion:  If you have access to another working PC and can do a download and you have a flash-thumb-drive of at least 8 GB   ....then...

you can make a bootable USB  that can later be used to get to a Recovery Environment.

See  about making a "Media Creation Tool"  USB    / get a save the tool from Microsoft

Get t from this link  https://go.microsoft.com/fwlink/?LinkId=691209

Once you have that, you will use it to create the bootable USB

More detail info about creating that USB   https://www.tenforums.com/tutorials/2376-create-bootable-usb-flash-drive-install-windows-10-a.html


Let me know once that has been created.  The tool is not intended to install or update Windows.  BUT rather to make use of Advanced options to see about getting To SAFE mode or else to a Command prompt  ( a.k.a. Windows Recovery environment ).

No problem! After all, many people had similar issues while using the newest version of Windows, I think it's up to Microsoft to fix their system.

As of the computer, I ended up changing the motherboard since none of the devices worked after forcing a reboot so many times.

I'd like to thank everyone here for the quick responses, I'm sure that if my MOBO wasn't messed up I'd be able to follow these steps.

How is the situation after you installed the new systemboard hardware ?   Are you able to get Windows started normally ?

If you have Windows working in normal mode,  take a few minutes to make a Recovery disc/USB
