Hi there and welcome
This stop error code refers to a memory error.
I want you to first do the following please Cindy
Remove the power charger and hold the power button down for 60 seconds then release.
Then connect the power cable, power it on and tell me if it still gives this error please.
Power it off.
Then power it on and keep tapping F11 until you get to the recovery manager
Can you get to this?
