Personal Computer for college

Hello everybody. At first of october i'm starting my first year of college. I'm studying to become mechanical engineer. Its covid-19 time and both of my parents lost their jobs because its crisis in the country. I need personal computer for my collage. I need pc with good graphics card and processing power for programs like autocad and solidworks and etc. I can get loan from the bank on 2 years but i don't have a way to repay the bank. Because i cannot work and be on collage on the same time. So if you want guys i will appreciate your support and help in this very nasty time for my life.
