Troubleshooting BSOD's

[Pedro_The_Swift]

After getting my Z390 Aorus motherboard back from warranty I was a bit keen to get it running,,

However, 5 short beeps greeted me at startup, with no bios.

The collective intenet wisdom is a bad cpu, so I swapped it into my backup that had served me faithfully while the MB was away.

This fired up ok, ran windows, the net, in fact everything EXCEPT
the CPU test in "PERFORMANCE benchmark"
where I got, in order,
BSOD- "machine_clock_exception"
clock_watchdog_timeout
a HARD lockup
another Clock_
and a "system_service_exception"



any thoughts?

Tried doing the diag on harddrive and ram when you get the bios up?

Reason i say this is i have had faulty ram sticks give me tons of grief like BSOD.
Also remove any usb devices during tests to remove them from the equation.

Dunno if this will help: Blue Screen of Death on Windows 10 (https://askbobrankin.com/blue_screen_of_death_on_windows_10.html)

also:


By default, Windows 10 is set to auto restart after a BSOD. It can be hard to diagnose the error message on the BSOD because the restart can happen much too soon. I always disable this setting when using Windows 10. It is found under System Properties, Startup and Recovery, System failure.
