Overrun PC
What should I do?
My PC is completely filled up with stuff, I have a 2TB hard drive that I have used a TB of already and I think it has had a consequence on my PC.
Should I format it or should I just leave it as it will not make a difference?
Just go through things like your documents and program files and anything that you dont want just delete.
And uninstall any programs you dont need
What you really need to do is go through your things, find anything that you want to keep, and then format. Deleting a few files here and there can help, but a fresh start with only the things you need will be much better.
