Windows 10 pro "diagnostics" boot up mode login blank

[Valuable Gamer]

Alright so
I noticed that I had a virus called "svcvmx" in my pc and i tried everything safe mode ,changing permission , anti virus (this resource is already in use)
I've tried everything to remove this virus nothing worked
Then I open "msconifg" and I picked "diganostics" for boot up now whenever I open my pc the login page is blank(can't enter password nothing is showing only the power button and internet which isn't connected) I've tried
"Shift+restart" and that didn't work I honestly tried everything even the diganostics option when clicking "f12"
I have dell window vista

Any solution ?

Did I read correctly, you are using Windows VISTA ???
I really urge you to change it, it's one of the worst ever.
Even Windows XP is better.

Now, back to your problem, try this:
- turn off computer completely
- turn on computer, wait just a few seconds, start pressing F8. F8, pause 1 seconds, F8..... and so on
- the Windows boot menu should appear, select Safe Mode or Last Known Good configuration.
- if it starts, try to use System Restore to revert back a few days/weeks, when it was working.
