I own a cellphone and computer repair shop. This morning a customer brings me his HP 2000 laptop in and says the following "It was running win 7 and I upgraded it to win 10 and I didn't like it so i downgraded it back down to win 7 and now the keyboard and mouse wont work". He asid the downgraded it via a link that said something to the extent of "don't like win 10 revert to your old OS of win 7".
I figured maybe a driver issue so it's a easy fix. I started the computer and figured if i plugged in external it would work but nothing. Neither internal or external is working. This includes safe mode also. When I went to boot Hirens cd the internal keyboard wouldn't let me select the boot cd but the external does. Once I get into hirens and boot mini xp both internal and external work.
I've run malwarebytes in mini XP and returned nothing.
i'm currently running kaspersky rescue CD and scanning and internal and external keyboards work fine.
I know i should'nt run combofix but i just opened it in mini xp to see if it returned anything. The program opened a blue command window and started scanning and then returned a message to the extent of "root-kit found need to restart". I'm completely stumped on what to do at this point.
I figure somebody is going to eventually tell me to wipe and reload but to me that's avoiding an issue and not facing it. I want to learn how to repair these issues if possible not run from them.
