Question computer not booting up after CHKDSK

[darvarn]

So I decided to run CHKDSK after I saw on the internet that I should do that because my C-drive memory was filling up randomly. I feel like it keeps turning off and on because the lights on my keyboard keep turning off and on. I entered a command in the command panel and it said to restart my PC. So I did. It hasn't turned on for about 5hours from now. Im on windows 10.

what is the exact command?

chkdsk C: /f /v /x

 

[rgd1101]

so you shut the pc down. try turn it back on?
