How would I go about completely removing everything, OS, docs etc from my HDD so it's like they never existed on it?
I wish to know as I want to sell my PC and want the new owner to be able to install whatever they want on the HDD

I would use a program called DBAN (Derrick's Boot and Nuke) Just download it, burn it to a CD and restart and boot from the CD. This programs wipes the hard drive several times over. This is probably your best choice.
Just google DBAN

Spinrite, from Gibson Research, has functions that will erase your hard disk and write 1's and 0's multiple times to follow government guidelines for secure erasure. It also does other great stuff for servicing hard disks.

The only way you can completely leave the data undiscovered is to buy a new HDD. Many programs will claim to wipe it but there will always be a trace. When selling a PC I would strongly recommend replacing the HDD.

A tool like dban will work fine. PS you don't need more than 1-2 passes. After 1 pass, a software tool will not be able to recover any data, though other recovery methods can still work (eg a data recovery company that goes through the process of using special machines to examine the platters)
But that process may be incredibly expensive and unlikely to be done by a random person buying a used PC from someone they know nothing about.
It might be different if you were the CEO of Intel and is known to have schematics for various chips on the system and are now planning to sell your laptop to get a little extra cash in order to afford a new laptop with the overpriced Intel SSD, then you may want to do 7 passes with DBAN.

Yes its true that even after emptying trash/recycle bin the data remains in our hard drive not in ready to read for but can be recovered using some data recovery software.
The permanent solution is to fill 1s and 0s with some disk wiper application.
