Weird startup after shutdown

[veno1g]

Hello guys, i am new here , i'm into a big problem and i can't find any fix, please help.

PC : i9 14900k, rtx 4080, 64gb ddr5 g skill , m2 nvme, msi mpg z790 carbon wifi, msi mpg a100g psu, aio ekwb nucleus 360.

Problem: at every shutdown longer than a few hours, when i start the pc is moving like super slow, laggy like in 5 fps, a couple of restarts solve this and is working just fine.

i searched the entire google for a fix or the problem but i was unable to find the reason and the fix.. didn't work

i tried a fresh windows install, i did numerous stress tests, all drivers, bios updates, firmwares are updated, the cpu seems to be ok, i never had a crash or bsod, i had a cinebench run for 10minutes  with a max temp 85c and 35823 points. this started randomly, nothing new istalled, nothing added to the pc, was just random 1 week ago.

this is a video of the issue: 

ty tho...

For how long have you had this pc?

The bios updates with the Intel microcode is only preventing from new cases of degradation. It doesn't fix or repair an already degrading cpu.

So it could be that your cpu were getting bad and the bios update came too late.

 

If the pc is brand new it could be something else.

Don't do anything that could void the warranty. Perhaps you could return it to the reseller, let them test it and then give you a replacement.

is like 6 months old, i didn't see degradation or something like that..it's just pass all tests, run all games. it's self built pc.

If you use Restart instead of Shut Down, does that fix the issue? If Fast Startup is enabled, the Shut Down feature is basically replaced with hibernation. Which sucks balls. So if Restart fixes it, disable Fast Startup.
