Attempt a clean installation of your OS preference.Other than that, my guess is that your machine is dying, and no amount of money would fix the components.Computers are really quite inexpensive these days, so I would recommend that you consider that choice first.Best of luck.../rgc

For the past three years I have my computer been set with with multiple 
virtual machine assigned to a GPU using QEMU/KVM and VFIO. For the past 
year CentOS as been the host computer, it has been reliable.  This 
summer I switch to the Centos Enterprise package, it been work for 
several weeks until Friday, sometime over the weekend the console 
portion of the boot process does not display.  I have one Windows 10 
virtual machine book, but the EFI boot screen does not display and the 
Windows circle do not dance on the screen. I am unable able to boot my 
other virtual machines, they get stuck the monitor just flash on and 

I performed a major upgrade on the 4th of July it work through Friday.  
I have used the history command in yum to undo the update the problem 
persisted.  I have qemu-kvm-ev-2.10.0-21.el7_5.4.1.x86_64 and 
libvirt-3.9.0-14.el7_5.6.x86_64.  I can post a configuration if you 
think it will help, I have regenerated a xml file from partially working 
Windows 10 machine. What has changed in the last week. I have tried many 
things but not sure were to go from here.

Thank you
