Time to Change My Comp?

It feels like it's time for me to change my computer. I just had to reformat my computer again for the 3rd time in the past 6 months (that's very frequent imo). It becomes more frustrating when you have work to do on the computer that needs Internet, only for it to not perform properly when you need it most =(

I don't know what happened to the driver but somehow, my computer is not able to connect to the Internet (for God knows what reason). I ended up without Internet for 24hours before I decided to reformat the computer. Now, I'm left without that many software in my computer. Have to collect it slowly once again

I suppose I need a strategy to enable me to reformat my computer very fast. I was thinking of keeping my Drive (C) light on data (only program files) so that I can reformat it almost immediately when problems come up.
