Hi Howie,
the new ASUS notebook with Windows 11 works perfectly, is very fast, but after some 30 - 150 CW QSOs fails. Goes to black screen and restarting.
 Error codes are different: 0xEF, 0x1A,  0x154, 0xA, 0x1E. I also registered: What failed ntoskrnl.exe
Could you advise how to fix it. I tried CCleaner, no success
Best regards  Jiri  OK1OA

Hi Jiri -

For starters,

WHAT  CHANGED ? Windows, TR4W level, or Hardware ?

From a TR4W standpoint you can run debug (TRACE) which will write out to tr4w.log in your TR4W directory.

Keep in mind the failures are not being reported by TR4W. 

You would probably have better luck looking into the windows failure codes.

--My guess is a resource constraint or failure-
but you can ctrl-J DEBUG (trace level) and check results written out to tr4w.log.

Typically, TR4W (or Windows) would have heard of this failure a long time ago.
Additionally the fact the failure does not occur until 100+ qsos are logged is indicative of
some sort of hardware resource failure.

73, Howie

some additional thoughts. 
it would be helpful to better quantify the failure; have you tried running the windows and acer diagnostics ?
Try importing your largest log.
Does the laptop run hot  ?

What to try
  • Boot into Safe Mode and see whether the crash still happens; if the system is stable there, a bad driver is likely.

  • Update or reinstall GPU, chipset, Wi‑Fi, and storage drivers from Acer or the device vendor, since mismatched drivers are a common trigger.

  • Run memory and disk checks, because faulty RAM or SSD issues can also show up as ntoskrnl.exe crashes.

  • If the problem started after a Windows update or new software, remove recent drivers or low-level utilities first.

Excellent. 
It might help other laptop users if you could share the solution ?

Hi Howie,
thank you for help. In my new laptop some drivers were outdated. Now I'm testing the updated funcion. From the Jaro's conversation is not clear what he really did to fix the problem.
