Windows 10: Blank screen on cold boot

I have a Lenovo Ideapad 700 15-isk laptop with windows 10 professional x64 installed.I used to have a very old windows installation which used to be a windows 7 installation that I updated to windows 10 when it rolled out and that I kept maintained updated including 22H2 update and had no issues.I decided to go for a fresh installation and I downloaded the 22H2 version of windows available on Microsoft, created a bootable usb and made a fresh installation.

blank screen at boot up 4850 could it be voltages?

Hello everyone *Smile
I've been getting a blank screen at cold boot up the first time i turn my pc on until it gets to desktop also if i leave it off for a couple of hours or leave it idle at desktop for more than a couple of hours it goes blank again,with all these i get a flashing green power light on my monitor. I was looking at the voltages in RBE in the clock setting and see at boot [clock info 00] the voltage is blank, that includes brets bios's and the default bios as well, as well as being blank in 03 06 09. Ive looked at bios's for the 3800 series and they all had voltages of 1.3 in the boot clock.

Could this be why i get a blank screen on a cold boot or after a couple of hours of inactivity,would it be safe to put a voltage value of 1.084 or something similar in the boot clock info 00?? Would if cure my blank screen problem?

Ok, let the powershell command run overnight
If the command didn't solve the problem, the try these steps in order:

1. Disable superfetch service
   • Empty the following folder c:\Windows\Prefetch\
   • Restart the computer
   • Si ça ne marche pas, passer à l'étape 2;
2. Disable the AppXSvc from the registry: change the "Start" key value from 3 to 4 (see the screenshot)
