There was a storm here the other night and before the computer got shut down properly, the electricity went out. It was out for approximately 4 hours. Upon it being turned back on, the computer was booted and used as usual with no apparent problems. The next morning, however, when someone tried to use the desktop the chkdsk scanned, rebooted and the sign in screen came up. After putting the correct credentials in, the welcome screen clocked for a moment and then went black instead of loading windows. The screen seemed to freeze the computer and had to be shut down improperly by the power strip. The computer was turned back on and tried again with the chkdsk coming back on and instead of letting it scan again, the user stopped the scan and was able to sign in properly. They used the computer for a while and all seemed okay. Later in the day another person tried using the computer and the chkdsk ran again. I believe they were trying to get into Netflix when chkdsk cut in and ran. It rebooted itself afterwards and the sign in screen came up. I told the person to leave it be and I put the credentials in. It worked and windows loaded. Afterwards, I turned the computer off properly. It shut down with no errors.
Now since I was not the one who encountered it the first time I tried logging in. I turned on the computer from the proper shut down. The computer loaded up, the sign in screen came on and I put in the proper credentials. After which, the welcome screen clocked for a moment and then went black. I waited to see if anything would happen - nothing did. I tried clicking the mouse, nothing happened and I had to turn it off by the power strip because I could not turn it off properly. I tried a second time and when I turned on the computer chkdsk came up and scanned. Nothing seemed to be wrong and it rebooted itself. After the reboot I tried logging in with the same problem with the black screen occurred. The computer had to be shut down improperly. Windows will not load.
I'm confused as to what happened. Did something somehow get corrupted? Everything connected works i.e. router, modem. The tower is not making any weird noises. I just cannot get past this blank black screen.
