Same thing happened to my 7 system about 3 months ago. Hmmm.
Welcome to the club!
I’m running 10 got a string of updates and afterward it has been a total mess won’ start half the time even have to unplug the power cord and remove battery and when it does the problems continue with it it throwing all kinds of unwanted pages up and this is on a one year old HP
Any Win7 users: 1) Make a complete backup.
2) Have Win7 make a startup recovery CD
3) Turn off Windows Update.
After I came home one night a few years ago to see my computer automatically upgrading to Windows 10, I shut the machine off and downloaded a program to remove all Win10 elements then I turned off the Windows Update and have been fine ever since.
If figured if Microsoft was so desperate to upgrade me *without my permission*, there had to be something about Win10 more important to Microsoft than it is to me. Some believe the difference is Chinese spyware.
I bought an extra copy of the Win7 operating system just in case I need to use it. It’s still unopened.
Incidentally, if you did make a startup recovery CD, punch F12 on bootup to change the boot sequence to your CD drive first before the hard drive and it will fix many problems that could have been corrupted in the hard drive OS. After running it from the CD a few times, you can reset the boot sequence to the hard drive and test to see if it boots again.
