am facing this problem on windows 10 that on cold boot it freezes on the windows logo and spining dots.
it was working fine before on 1809-1909 and last 21h2
. but i faced another problem before this that got fixed but after the fixed now i face this am not sure what could be the reason or how to fix.

it was working fine until one day when i decided to clean install windows 10 got official iso image and used rufus for usb. when it booted from the usb started the installation and it copied all files as you know when this is done the pc will auto restart automatically after 8 seconds, then restarts and starts installation you add name and password ect and takes you to desktop. well for me after it restarted it froze at the dell logo. pressing f12 or any key would do nothing i would not go past he dell logo. the blue bar will fill up then freeze. could not enter bios or diagnostic laptop was bricked. after many search on the web here i found someone with the same laptop model and the problem and he fixed by manually flashing the bios with programmer ch34a1.

so i bought the programmer got the clamp with and decided to get it fix as well. but here comes more problems. am a newbie. there are 2 chips and 2 files for bios. so when i was readinf the chips i manage to read 1 of them and attempting to read the other one i could not grab the chip anymore with the clamp. it wore off the plastic. so while i was trying i removed 1 or 2 resistors smd next to the chip. lucky i had older board. since i live in small town i suffere from panic attacks i have no income and rarely go to city. i took both motherboards and have a local shop solder the missing resistors on the board am planning to use. i was told it had to have a thermal station something like that not really sure. so he did solder the missing resistor or transistor on the other board . he also removed both chips. wich he then solder them to the programmer. i took them home and program it both chips and had him solder them back on the mother board.

i assembled back the laptop and the freeze on dell logo was fixed. now i could go into bios. get past the dell logo and got it to boot into windows remeber it never completed installation so booted to windows installation to complete add name or password but i decided to stope it and decided to do a clean installation.
so here is where am facing this new problem.

windows 10 freezes at the windows logo and spining dots.

i did i clean installation added name and password and booted to desktop not connected to wifi.
i create a new system restore point. i can use laptop just fine. i can restart laptop and takes me to desktop and works fine.
but if i shut down laptop and turn it on thats when i face the windows logo spining dots then freeze never gets to log in screen. force it to enter advanced recovery. in there i can go to restore point and restore created point it would restore the created point finish and restart and laptops enters to desktop just fine.
if i enter to advanced recovery and then enter safe mode boot to desktop fine. if i do a restart it also takes me to desktop fine normal mode.
so it only happens when i shut down laptop it freezes.
i have updated windows upto date and still face this. do stress test all fine. do benchmark on both video cards and work fine temps are fine.
in dell diagnostics it passes all tests.
it does this on win 8.1 win 10 and even tried win 11 all freeze at spining dots
but i also tried windows 7 pro. and on win 7 i dont face this i can restart and or turn off laptop and always boots to desktop..
been trying to find out why for 2 weeks aready please help.
could it be related to ressistor smd that got removed.? or the bios flashing.?
thanks
