Windows 10: Blank Security screen after 15 minutes of boot

Hi , i am on windows 11 and have a problem that Windows Security will populate properly after boot, but after a period of time if i try to reopen it, it will be blank. The only clue i have is if i also open an instance of Windows update at the same time, then Windows security will populate.Things i have tried:Full clean install of Windows 11New user profileAll the fixes for blank Windows security i have found on this site ie reinstalling and resetting windows security.Also i have a local account, would that make a difference.

Secure boot violation after update and blank screen

Hi, my laptop (ASUS TP550L running Windows 10) updated last night, and when I turned it on this morning the screen immediately displayed a Secure Boot Violation message (invalid signature detected. Check secure boot policy in setup) - clicking ok sent
me to BIOS. Looking online told me to disable the secure boot control, but doing so resulted in the computer going to a blank screen and not doing anything despite my waiting for about three hours. So I re-enabled the secure boot control and am back to the
secure boot violation message. I'm not sure what my options are - if a reset is plssible, what I'd lose, if anything, or if I have another source to boot from given that I don't have a CD or USB to do it from - so I'd appreciate any help or suggestions.

 

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?
