did you install park control? i read warning in video saying not to. Not sure about game booster
On another PC, download the
Windows 10 media creation tool and use it to make a win 10 installer on USB << its just a bout disc
try running start up repair
change boot order so USB is first, hdd second
boot from installer
on screen after languages, choose repair this pc, not install.
choose troubleshoot
choose advanced
choose start up repair - this will scan PC and maybe fix this - will ask for logon info
see if you can get into safe mode:
boot from installer, on 2nd screen after languages, choose repair this pc, not install
choose troubleshoot
choose advanced
choose start up options << sometimes this menu isn't here which is a pain.
hit the restart button
choose a safe mode (it doesn't matter which) by using number associated with it.
PC will restart and load safe mode
If it boots to safe mode, you might want to set boot to normal again instead of using all cores as that can mess up start as it loads processes out of sequence
right click start
choose run...
type msconfig
go to boot tab
click advanced options
untick number of cores used at boot
rest of programs looked fairly safe, though ccleaner can clean files your PC needs, regardless of his warnings.
