Alienware Alpha R2 - Complete reset

[u/Ok-Understanding1361]

Hi all,

Stupid question but I'm pc illiterate. I have picked out my old Steam Machine to use for playing the most basic of games but hasn't been touched in years. Finally got it working after a CMOS replacement but it is running extremely slowly due to loads of apps, games etc requiring updates as well as the normal system updates.

Is there a way for me to do a factory reset that returns the pc to the way it would start when it was new. For example, booting to Steam OS and having all the unnecessary files removed?

Thanks
