Playing NFS (it was the version which had the McClaren car), few other games and watching some movies (CD player) It wasn't my computer though. It was my cousin's and I used it while he was working. I think I broke it couple of times (windows 95) to get the BSOD.

I bought my own computer only when I started working. My family couldn't afford one before that. Luckily I had good friends in college who let me use theirs for course work.
