This happens every 30mins to 1 hrs in normal mode.

Mac will restart on its own. Sometimes properly, other time with half blue screen during apple logo and screen turns off/black.

In safe mode also same but it restarts properly. screen will be like blue contrast but then returns to original.


Also recently i had switched from hdd to ssd (don't think its because of this)



IMac details - 4k 21.5inch 2017

I think the only way you're going to rule out any storage device as the cause of the crashes is to disconnect it. It's one of the suggestions in If your Mac restarted because of a problem - Apple Support. Step 2.
