Tried resetting my pc and didnt work

So I was trying to reset my pc because its so slow i could barely even play a game on it and i did the reset this pc option and didnt work because i need to have a windows installation media which i have in my usb plugged in my laptop and didnt even work. I tried some other stuff but its a hassle to do it and just waste my free time for finding a video resetting my laptop anyone got any ideas to reset my laptop or desktop?

 

Cannot sign in microsoft account.

My device: Lumia 520. GDR2.
I cannot sign in my Microsoft account on my device. It didnt say any error but Microsoft account is not listed in Email and account list. When I click add button, it will show microsoft account option but after press sign in, it is still not shown in email
and account. Another problem is i cannot delete facebook account. Error code: 0x83cf1202. I have tried as suggested here: http://support.microsoft.com/kb/2475837/en-us#step0x83cf1202 but as my Microsoft account is not shown, I cannot do step 6.

Any suggestion?
