I'm wanting to retire my desktop. it's about 10-15 years old, and I never use it. the network adapter seems to no longer work too, so I can't get online. it's pretty just sitting there. I've thought about using my nes/snes/psx classic and retron 5 in its place. they're close to the surge protector. I only plan to plug in what I'm about to play instead of powering everything at the same time. I already have enough plugged in. anyway, I want to wipe the internal hdd clean. I'm not sure if I can use a cd/dvd or even a flash drive. the computer works (I think). I've replaced the hdd, optical drive, psu, and ram a long time ago when the originals went bad. I think it's finally time to retire it though as I only use my laptop. can anyone recommend a program to do this?
