Constant Crashes and restarts (WindowServer, Watchdog)

I left the computer alone for 30 minutes and when i tried to wake it up, the screen turned on with the error message in multiple languages and it restarted.

The error report that it sends to Apple contained this:

And the console report that i'll need to shorten is this:

My upper right corner (maybe it helps)...

My energy saver settings:

I hope this is helpful... and if someone has the same issue, comment...

I left my iMac alone for a half hour, when i tried to wake it up it the screen was black (with back lamp on), it did not respond and rebooted itself with the multilingual crash message... When i logged back in, this is the error message that was sent to apple:

It just crashed and the report came up with the processor error i said...

*** MCA Error Report ***

CPU Machine Check Architecture Error Dump (CPU: Intel(R) Core(TM) i5-7400 CPU @ 3.00GHz, CPUID: 0x906E9)

CATERR detected! No MCA data found.

I think this should be the last thing I try to document in this forum.

I changed my settings for the display to never turn off and set a screen saver that covers all the screen (itunes' album covers) and has a clock on it.

I was in the room with the iMac and was seeing the screen on with the screensaver running,

when i tried to use it i noticed it was frozen.

The screen froze at 4:08, it was around 4:15 when i noticed... i pressed random keys on the keyboard and moved the mouse and it quickly displayed the multilingual crash messaged and rebooted very fast (that SSD really helped with that)

Checking the console, i found FOUR crashes...

The one at 4:09, from WindowServer contains:

The report from bluetoothd at 4:13:

The third one, from WindowServer at 4:14:

The last one, from WindowServer at 4:14:

The report generated after reboot that was sent to Apple:

Crash before i could even type my password to login...

I tried updating to 12.5... it seemed to work, but didn't...

I installed 12.5 in another drive and migrated my files and still crashed...

But i noticed something, I changed settings for the display to take longer to turn off and the crashed seem to delay.

Yesterday i moved the slider in power setting further right so the display won't turn off, and did not have any crashes since then.

Maybe the issue has something to do with display controller or card, and crashes when the display turns on or off, or when switching to different modes... i don't know... i'll let you know if the crashes stop with this settings.

It crashed when i was on the Mail.app screen (the imac wasn't sleeping or anything)...

I think I've covered all situations when the crashes happen...

Here's the MCA error, but somehow it's longer this time...

Didn't work... took longer, but still crashed
