Suddenly nothing works windows 10.

[shadowkon626]

I was watching YouTube when suddenly it crashed. It kept crashing when I would try to open it so I restarted my PC. Now nothing works!! The start menu won't open, I can't click on anything on the task bar. The settings won't open, windows defender is turned off and when I click turn on nothing happens.

Ok as I was typing this on my phone I restarted my PC and suddenly stuff is working. But I still can't turn on Windows defender. I don't have any other antivirus turned on. I get a pop up window that tells me the programs service has stopped.

This has been happening for about an hour.

I just tried reinstalling Windows 10 and I get a message saying "there was a problem resetting your PC. No changes were made."

I also tried startup repair and I get the message" startup repair couldn't repair your PC"

How did it crash? Blue screen of death? Sudden freeze with a forced reset using the power switch? Once you're back in Windows, check to see what tasks are running in Task Manager (right click the Taskbar and click Task Manager). If the context menu still won't work from the task bar, you can also open Task Manager using the hotkey Ctrl + Shift + Esc.

Once in Task Manager, check the headings under the Processes tab to see if anything is under heavy load, and if so, scroll through the list of processes to see what is causing it.

My PC didn't crash, Firefox did. My PC boots up fine. I am now suddenly able to use Firefox and other applications, but I cannot turn on Windows defender. I don't have any other antivirus installed. It turned off on its own. I also can't install any Windows updates. I keep getting error 0x80070643

There isn't anything that's running under heavy load

Seems to be a common Windows Update error. Right click the Start button and select "Command Prompt (Admin)". Copy/Paste the commands below to clear the Windows Update cache (note that each command is on it's own line):

net stop wuauserv
net stop bits
rmdir /s /q %windir%\SoftwareDistribution\DataStore
rmdir /s /q %windir%\SoftwareDistribution\Download
net start bits
net start wuauserv

If right click the Start button gives you the option to open PowerShell instead of Command Prompt, use the commands below instead:

net stop wuauserv
net stop bits
del -path $env:windir\SoftwareDistribution\DataStore\* -force -recurse
del -path $env:windir\SoftwareDistribution\Download\* -force -recurse
net start bits
net start wuauserv

Once this is complete, open Settings again and try checking for updates.

So it looks like things got worse. I restarted my PC and now it's going through disk error repair. The thing is it just gets stuck at 7%. I left it on over night and there was an error. Everytime k restart my PC it just gets stuck during the repair process. Right now it's been stuck at a screen that says "repairing disk errors. This might take over an hour to complete." But there is no percentage. There is a spinning circle so it's not frozen. It's been like that for about an hour.

What can I do now? I'm guessing I'm going to need to do a clean install of Windows, but how do I do that if my PC won't even start up?

Depending on the problem detected, and the size and speed of the drive being scanned and repaired, it could take several hours. Best not to interrupt it, as at worst, it will make the problem worse, and at best, it will set you back the time you waited in each instance before rebooting, since the process will need to start over from the beginning.

If it does come down to a clean install of Windows, you can grab a copy of the Windows 10 Media Creation Tool from another computer and let it download and set up the installer on a USB flash drive. The drive should be at least 8GB in size. Once set up, plug the drive into your faulty system and boot from it to begin the install.
