Correção de texto: My first computer

Hello People, espero que alguém possa dar uma revisada básica, Thanks

My first computer was actually my sister, but I used to use the same way, It was one of those very old computers with a heavy and huge screen and a CPU that was not different.
I remember who spends most of time playing online, or when the old dial-up internet did not work, I used to play the computer games, as solitaire game and that pinball game, which was my favorite.
It is true that took a long time to turn on, without speaking of the time it took to get a good connection with the internet, and it had that unforgettable and annoying sound that's everyone heard once in life os dial-up internet.
Compared with computer of today was a simple computer, with almost no memory that I could not do anything, but that time was more cool and interesting thing a child as I could have.
