This is almost certainly a hardware problem with the keyboard, so why would you think reformatting the drive, even doing it repeatedly, would fix this?

Here's some troubleshooting steps you can try: http://support.hp.com/us-en/document/c03738933

If you are experienced at laptop repairs, you can often replace a keyboard for $25 for a new one and a half-hours work. I have done this on older HP laptops.

But, if you're NOT, there is a serious risk of breaking fragile connectors and cables doing this -- so I do not recommend it.

Instead, I would recommend you hunting down a local laptop repair place to have THEM replace the keyboard. Sometimes, on some models, you have to replace the entire top surface of the laptop, not just the keyboard. So you should get an estimate of what is involved before you have the work done.
