Do you have an old computer or laptop knocking around that doesn’t work? Maybe it was full of viruses and you bought a new computer?
As long as there’s no data for me to back up, I will format your hard drive and install a fresh operating system for $50.
If you do have old documents and pictures and stuff that you want to keep then it will be a little more expensive but you’d still get change from $100.
The only thing is I would have to do the work in my workshop as it takes half a day 🙂
