A blue screen 0x7F code indicates a hardware conflict on your computer. In most cases, users install damaged, abnormal or incompatible hardware (especially memory), which will lead to such errors.

First of all, if you can still read the system boot, first enter the safe mode and check whether the hardware driver is normal. Secondly, we suggest that you check whether the recently installed hardware is abnormal, damaged or incompatible with your computer hardware.

If there is any abnormality, we suggest that you contact the computer hardware manufacturer as soon as possible to fix the problem.
