Blue page says "Your device ran into a problem and needs to restart".

Hi Huyluong , Hope you are doing well.
It seems that a device in your laptop isn't functionally too well.Did you change any hardware in your laptop or did you recently configured any settings or perhaps just any update or abnormal shutdown happened?
For now,try pressing F8 and then it should show startup settings. Then, press F5 To start the device in safe mode.If it does, Try entering device manager by pressing Win+R simultaneously and typing devmgmt.msc into it.Check if any device is listed in other devices category like this

Right-Click on the device and clik on update device to install any other drivers.

If you found nothing in device manager, then connect to WiFi and then enter windows settings by pressing WIN+I and click on Windows Update then check for optional updates

Also, Could you provide the specifications of your laptop?

Thank You

Shashank

Bonjour Saad1795 

Je sais que surement tu as déjà résolu le problème.

Jai eu le même problème et aucunes des solutions proposé ici ne m a aidé.

Nous avons réinitialisé le bio et réparé le système au démarrage et ca s'est lancé.

Merci

Seems Complicated
If it's your work laptop please give it your admin.

If not then please contact Microsoft because dell doesn't entertain any people out of warranty

(I also wanted but they didn't give so I reverted to Microsoft)

If you don't get any support from there also please follow the below steps but at your own risk~

Now I recommend a windows clean install which would actually delete your apps and accounts but it would keep all our files in a separate folder at C drive namely windows.old (this method rarely fails)

• Now connect your USB drive before starting your computer
• after starting your computer if the password screen opens up enter the password and press F12 You should get the screen like in Img-5131 
• It should Show Your USB drive's name there
• By your keyboard's arrow keys please select that key and press that enter key
• It should now load the windows installer
• Click on install now
• select the keyboard language, currency  and time zone
• click on next  and then click on custom windows install

Now you will have to apply some guess work and some logic too.Your Computer has a 256GB drive out of which the biggest partition should be reserved for your personal use so

• check the biggest partition
• and it's free space (it should be lesser than 232GB but that's just a rough idea and it heavily depends what you stored on your computer)
• That Partition will also be labeled 'primary'
• 

  You will get a prompt like this, Click On OK and then On next (if asked for a product key click (I don't have a product key)

  It will Now install windows. This Could Take some 5-10 Minutes.It will now restart and then load all the drivers.

Now you will get the OOBE Setup(this one's quite easy but if you need any help kindly contact me, I will reply as soon as possible but be sure to make it an administrator account)

After you created a account, Open file explorer (WIN+E) and then click this PC on the left navigation panel, You will get your Local Disk C drive click on it.

You will get a folder named windows.old open it, you will get a folder named users there

There you will get all your users account you created before re-installing windows 10.

Click on respective user account which you want to access, there you will get main folders like documents,downloads, pictures etc..

Now simple copy pasting work~

Cut the files from the respective folder(CTRL+X to cut) and then paste it in your downloads,desktops where ever you want into your current account.....

And Voilà! Your Files are back

most of the apps you installed can be downloaded from their websites

Also right-click on windows icon on bottom and select device manager

Look for any device with an exclamation mark like this 

If it is there download the dell support assistant from here Dell SupportAssist for PCs | Dell India and fire it up, then check  for drivers~

If followed the above steps correctly your computer would work as before...

I too reinstalled windows 10 through this way last month because of some updates not installed and the installation through windows also failed so I planned the clean install method and now it works just perfectly fine 

If you want any help please contact me...I am also available on zoom, Microsoft teams, skype and on discord please privately message through click on my profile if you want to get help that way or here it is also good...

I tried to help you to m full extend.. If it doesn't work please go to a nearby dell store because remotely helping isn't always the most effective way

BTW, here the Microsoft  support link, you can chat with them directly Contact Us - Microsoft Support

be sure to describe exactly what happens

I hope your computer gets repaired ASAP, I know that feeling when your computer doesn't work

Thank You

Have a Great day

Shashank Dahat~
