I am a 4th year student in Sofia University st. Kliment Ohridski. I am studying physics and due to the financial status of the Bulgarian state, my family could not afford buying a normal computer for me. Currently i am using Toshiba satellite with Celeron processor and 4 GB of RAM but this is far from enough. I cannot run physics computer simulations and cannot finish my project for my graduation. MS Office, MS Excel crash when i open more than 1000 points of data. Please help me upgrade my system so that i can have a decent computer with which I can finish my projects.
