Locks up completely? Monitor temps with HW Monitor.

Try updating to the latest BIOS available for the laptop and looking through Windows Event Log for critical system events.

Welcome to Tom's!
As Dudeman509 alluded to, I would also expect overheating. The issue here is that all the cooling in your laptop was sized for the lower power pentium chip, and the I7 is putting out more heat than the heatsinks on the laptop can dissipate, thereby causing the crashes.
Did you clean off the old thermal paste on the heatsinks and put new paste on with the new CPU?

Nothing to do with that, i don't know what Toshiba put in it to do that .I try with i3 2370M and the same shut down to every half an hour .

Is this the same laptop that you were having issues with in 2018? It still sounds like an overheating issue.

What exactly has been done to this laptop? Did you do it or did Toshiba do it? Try to give us as much detail as possible!
