PC, Monitor and Accessories to start a streaming channel

I want to start streaming on Youtube and Twitch. Though I am employed, its a very low paying job. My Monthly salary is 250 Dollars/Month out which 70 percent goes on paying Bills. I am currently owning Dell Inspiron 15R 5520 - Manufactured: September 2012
OS - Windows 7 basic (Pirated)
Display - HD WLED True-Life Display
Processor - Intel Core i3-2370M (2nd Gen) 2.4 Ghz
Chipset - Intel HM77 Express
Graphics Processor - Intel HD 3000
Storage - 500 GB HDD SATA 5400 RPM
Memory - 1600 Mhz 4 GB DDR3 RAM
Power Supply - Battery 6 Cell (Li-Ion) with AC Adapter

The fan stopped working from almost a year. Now its very slow, gets overheated and I cant do anything productive with this.

With your help I can start by doing something on my own. It would be great help if my donation goal is reached.

I sincerely thank all of you who would help me on this.
