"Hi, so there was a windows update pending but i rarely shut down my computer. Then a power outage happened.\n\nI couldn't boot the computer anymore, the screen was lit and receiving signal but only a black screen showed.\nAt first i thought the cpu died because the EZ debug led VRAM was lit up red on the mobo. Then I unplugged the power cable, and the day after the computer started, but i couldn't access my profile it showed \"user profile service failed to logon\".\n\nAnd when i go into debug mode by resetting the computer 3 times during the windows boot, it seems broken, i get the error \"sihost.exe unknown hard error\" then it takes forever to load I don't even have access to the explorer,  i can only access the task manager and it seems like one of my arrow key or home/end key is stuck as all the options keeps getting hightlighted one by one continuously.\n\nI tried deleting .bak extension on my sid in regedit and creating new user profile using netwizpl but i can't select  the newly created profile for whatever reason.\n\nI can only try a couple of things because after few restarts, the black screen at the boot comes back and i have to unplug and try a few hours later .."
