Computer keeps restarting after startup

@yongguanghu all of the stop codes "KMODE_EXCEPTION_NOT_HANDLED 0x1e" "page_fault_in_nonpaged_area (0x50)" "irql_not_less_or_equal (0xa)" "unexpected_kernel_error_mode_trap (0x7F)" commonly indicate a faulty or incompatibility hardware issue, most commonly caused with the RAM memory module. Other causes can include driver problems, malware, or even corrupted system files.

First thing to do would be to check your RAM and other hardware. Either pull your RAM, clean the contacts and/or replace your RAM. If you have multiple modules, you can try and swap those around or start with the minimum amount of RAM modules.

After that, check the solutions suggested by Microsoft about that particular error on here
