Please write to us with the following detail.

What do you refer when you say Locking up? Do you refer that your computer freezes?

I suggest you to follow the steps given below and boot your computer to Clean Boot state and then check if you still face this issue.

Clean boot: To help troubleshoot error messages and other issues, you can start Windows by using a minimal set of drivers and startup programs. This kind of startup is known as a «clean boot.» A clean boot helps eliminate software conflicts.

How to perform a clean boot in Windows

Note : Please refer to the section: How to reset the computer to start normally after clean boot troubleshooting of the Kb article to boot the computer in normal startup after fixing the issue.

Let us know about the status of the issue. We would be happy to help you further.

I’m having the same issue. I had to try several attempts to upgrade from Win 7 Home Premium to Win 10.

Once I finally got the upgrade to work, now the system crashes when I try to do virtually anything. I suspected maybe I needed to update some drivers, but when I try to do so, that too causes Win 10 to crash.

I’ve done the clean boot and that still does not resolve. My computer is now useless. HELP PLEASE!

The crash notes a BAD_POOL_HEADER

I tried to clean boot the computer, using the suggested process, but as the process went on, the computer became harder and harder to deal with. I was afraid it was going to become completely locked up, so we decided to go back to Windows 8.1 before that happened. Thankfully, the computer has been working well since then. I have noticed that several programs/drivers have updated since then. We are hoping that in a few weeks we can try again with Windows 10 and maybe the updated drivers will have fixed the problem.

I am no expert, but I would recommend you do the same if you still can.

These kind of pop-ups are fake alerts, trying to scam you into buying needless services/products.

Never ever call those phone numbers or fill in passwords etc.

If you can’t close your browser in a normal way: Open Task Manager (press Ctrl + Shift + Esc on your keyboard) and in the tab Processes end all browser processes.

You can also try Shift + Esc to bring up Browser Task Manager and kill the popup without having to close the browser totally.

Or Windows key + X and then Task Manager etc

And/or cutting the internet and/or shutting down your computer would stop all scam actions as well.

A good ad blocker should prevent pop ups/fake warnings/alerts/ads etc. Tracking blockers help too.

I use and recommend the free extensions uBlock Origin and Ghostery.

Most browsers offer the same or similar extensions.

Also go through your browser’s settings and adjust them to your wishes. For example, block 3rd party cookies etc.

You might also want to reset your browser(s), see if you have any weird extensions/add-ons.

If needed , follow the steps provided here:

You might want to read:

• explains various methods how to get out of those fake alerts etc
• includes Resources to protect your browser, privacy & help prevent browser pop-up ads and scams
• explains what to do when you keep on seeing these fake sites/getting pop-ups etc despite having followed the above mentioned advices.

Microsoft is sending my computer a notice that they have locked my computer

It’s a scam. Microsoft never sends such notices and never locks anyone’s computer.

Can you check the domain of the mail sender? Is it microsoft.com? These mails are generall phishing attempts. These are old methods to exploit the unsuspecting customers and sensitive information might be leaked including your computer and mail ID and other information being used for bad purposes.

Hi Patricia, well done for being suspicious, you would be amazed how many users fall for this!

This is a well known Tech Support SCAM — do not clikc into that page . . .

Press Ctrl + Shift + Esc to open Task Manager

Right click your Browser and choose ‘End Task’

All they are trying to do is get control of your PC, they will cause your PC to become corrupt and then require you to pay to have it fixed and even though you might pay them, they will not fix it!

Do not give them Remote Access to your PC
Do not give them any personal details
Do not pay them

It would not hurt to run a scan with the free version of MalwareBytes . . .

Once your PC restarts, you can remove MalwareBytes . . .
