Help me get a leptop for school

Hello.So i ve been struggling so much to save for a new laptop but whenever i got to the point of buying one something happend which made me lose it and start from the beggining. I m a student at the faculty of Interanational Relations and i have a lot of projects to do. My old laptop, which is ancient from the dinosaur time, lol (2004). It doesnt work anymore and it reboots by itself making me lose any unsaved data. Have you got any idea how many times i almost finished a project and it rebooted, making me lose all my work..its very frustrating.So i m not asking for a supernova laptop, but a decent one that doent reboot everytime i work on it. I dont know if i should mention that i also work because i have to pay my rent and college. I dont want my story to sound too dramatic, because it isnt, i have an average life and i know there are others with worse situations than me, but i really need this laptop in order to finish up my Uni projects and get my Bachelor degree. So, if u think its worth it and u can help me, Thank you and God bless you!
