Windows 10 laptop can take up to 20 minutes to boot up

katarina11 used Ask the Experts™
I am trying to help somebody with her laptop.  She has an Acer, Windows 10 and it can take up to 20 minutes to boot up or reboot.
These are the steps I have tried:
- Ran a full virus scan - nothing was found
-Disabled Fast Boot - didn't make a difference
-At an elevated command prompt I ran sfc/scannow - No integrity violation was found
-Disabled all 'High Priority' startup programs - did not make a difference but when we rebooted and I checked them they had re-enabled themselves..
-Checked to see if SATA drivers could be rolled back as I read that could be the problem - but she has Intel HD Graphics 3000

Next thing I will try is to disable all startup items and uncheck all services other than MS services and try enabling these one by one to see if I can pinpoint what is causing the issues.

Any other suggestions out there?  It's frustrating because I try requires a reboot and it takes forever to come back up...

It looks like some services has problem to start or not starting at all
Go to Computer Management /Services and check if services selected as Start Automatically are working or not.
Make note what services are not started.

Also check System and Application event log and compare with time after reboot.
I think you can find some clue about why computer is not starting in normal time
Once booted up, how does the laptop run?   If you open a browser does it work?  If so, try downloading Malwarebytes and superantispyware to find evil stuff a virus scan misses.

Safe place to get them is from or bleepingcomputer.  Run the data updates for each, if you can.    Check the scan rootkit option in malwarebytes.   Then run the scans, follow directions to nuke anything they find.  I wouldn't worry about false positives at this point (they don't have many anyway).

Once those scan clean if you still have slow start up, Try Zemana antimalware also available from bleeping computer or  They use a huge cloud based malware database.

I agree with the suggestion to do a repair install.

Is the laptop trying to access some other networked system that it cannot?

Another check you can perform, in particular if it doesn't last that long until she gets to the login screen: log in with a different user (you might have to create first). That shows if it is an issue with the machine or user setup.

Deja vu, right John? :)


John Hurst and some other experts helped me recently with a Acer laptop with Windows 10.  Turns out the hard drive was the problem and replacing it was the solution.  Here is information they provided me when helping me figure out the solution to my problem.

Basic information when trouble shooting a laptop.

The hard drive was the problem.  Replacement and using a 16gb usb thumb drive I was able to reinstall Windows 10 with ease.

Good luck getting this laptop fixed for your customer!

i ussually start by checking the disk  - cheap Acer models come with 5400 RPM drives = slow; you can replace it with an 7200 RPM model, or best an SSD - if the budget permits
run the manufacturers diag on the drive, to know it's status; i use the UBCD for this :
Hardware diagnostic CD    UBCD
go to the download page, scroll down to the mirror section, and  click on a mirror to start the download
Download the UBCD and make the cd   <<==on a WORKING PC, and boot the problem PC from it
Here 2 links, one to the general site, and a direct link to the download

since the downloaded file is an ISO file, eg ubcd527.iso - so you need to use an ISO burning tool
if you don't have that software, install cdburnerXP :

If you want also the Ram tested - run memtest86+ at least 1 full pass,  - you should have NO errors!
For disk Diagnostics run the disk diag for your disk brand (eg seagate diag for seagate drive)  from the HDD section -  long or advanced diag !  (runs at least for30 minutes)      

**  you can make a bootable cd - or bootable usb stick
*** note *** for SSD drives  use the tool from the manufacturer, like intel 's toolbox :

for completeness -here's how i handle disk problems :

==>>****in order to be able to  boot from CD or usb - you may have to disable secure boot in the bios
In todays world there is a lot going on at startup, not only are the Virus checkers etc all checking that everything is OK, so is Windows updates doing the same thing, you will probably find that the disk is maxed out IOPS wise (Blue line at the top in resource monitor).

I had this kind of problem on my laptop running W10, and upgrading to a SSD (Samsung 840 Pro) solved the problem (the cloning software provided was easy to use)

Of course it might be a disk problem so run the diagnostics first, and you might also note that 4GB isnt enough for W10, you need at least 8GB!

Im gonna go out on a limb here and say if a fresh install of windows does help it sounds like a dying hdd to me.
