A few days ago I bought a recognized brand, new PC that came preloaded with WIN 8. Nice box with 8 gig of mem and 1Tb HD. Big step up for me from my 10 yr old Dell with WIN7. Over the last few days I upgraded to WIN 10 and moved a lot of files and info files from the old to the new PC.The new PC has developed a problem which I'm pretty sure is PS related. I've got 10 days left to return it to the vendor. I'd like to remove my files before I return it. What's easiest way to go about it? Just format the drive? It's a big box store and they won't question the return or try to boot it when I return it.
