Windows shuts down

Hi I have kind of an ugent problem. When I started my pc today it sudenlly started to shut down with the stop codes system_service_exception and memory management. I already tried scannow after 100% it returns with "Windows recource protection could not preform the requested operation" and dism returns with error Code 50 dism does not support servicing windows pe. I have most of my schoolwork on it so it would be the best if I dont need a factory reset
