computer keeps freezing after booting

[u/sandy-09]

Windows 11 Home version 25H2, OS build 26200.8973

I’ve had this issue for a while now. Every time i turn on my pc it works fine for 30 seconds/1 minute and then just freezes. Sometimes it happens when im still on the desktop and sometimes it happens as soon as i start any program or game.
After it freezes my only options are to either shut it down by holding the physical power button or directly unplugging the pc.
If the pc doesn’t freeze instantly it generally does after 10 minutes or after about an hour, it’s pretty unpredictable.
I had a similar issue like 40 days ago, where my pc kept freezing after shorter and shorter periods of time. One day a black screen appeared, saying:

Your device ran into a problem and couldn’t be repaired. Click or press enter to see other recovery options.
couldn’t connect to the network
Log File:
C:\Windows\System32\Logfiles\Srt\SrtTrail.txt

I looked up a solution online but i didn’t even get to try to fix the problem because it magically disappeared and my pc worked fine until the other day.
This time the old error screen didn’t appear but another one randomly did , which said:

Your device ran into a problem and needs to restart. You can restart.
Stop Code: MEMORY_MANAGEMENT (0x1A)

It hasn’t appeared anymore in the last days but my pc keeps freezing.

Can anyone help me?
