Hi Shana and welcome to the forum
Sorry to hear about your problem, but without more specific information about the Make/Model of your computer, we can't really help you very well. Have you attempted to use the built-in
SYSTEM RESTORE utility in W7? It will undo any changes your son or anyone else made to the computer such as bad programs installed or a virus/malware attack and get your computer to boot into Windows properly. This program is very easy to use and there are numerous videos you can find in YouTube by using Google search to walk you through this.
However, and it's a big however, any kind of software repair can cause complete system failure, and therefore
YOU MUST HAVE ALL PERSONAL DATA YOU WISH TO SAVE ALREADY SAVED TO EXTERNAL MEDIA PRIOR TO ATTEMPING ANY SOFTWARE REPAIRS SUCH AS YOU FIND ON THE INTERNET HERE AND ELSEWHER PRIOR TO PROCEEDING, IN ORDER TO AVOID IRRETRIEVABLE DATA LOSS!!! This is really important so, that's why I bold it and put it in
RED; better to warn everyone and not just assume that they already know this as most beginning computer users do
NOT know this!
Now that we've had that discussion, I will tell you that the System Restore program can fix about 35% of boot problems on Windows computers. It's not a 100% guarantee-and there is inherent risk in permanent data loss, if your data is not properly backed up; hence the
Giant RED warning above! !
With your data safely backed up and protected this is the easiest thing to try to fix it. If you cannot run this repair, or the backup needed to protect your data on that computer *in the case that you
DON'T have it backed up*, I suggest you pay a licensed Computer Tech independent or at your local repair shop to fix it for you. In the case you decide to attack this yourself (we call this DIY); I wrote a very good
Troubleshooting Guide that will produce positive results about 85% of the time for you.
Here's the link to my
Guide:
Windows 10 - Unclickable Task Bar
This guide contains very detailed step-by-step instructions, sort of like how to put in your own garbage disposal, that will walk you through what you need to do. If you decide to go the DIY route, you have some advantages besides the obvious one of saving yourself some bucks.
What you will need to do is to print out the entire Guide, it's
6-8 pages in length, on a different working computer with an Internet connection and a printer to get yourself a hardcopy of the Guide. Take this Guide back over to your crashed computer and keep it in front of you as you go through the troubleshooting steps. A lots of my students use this hardcopy to take notes on.
One of the big advantages of doing this is that if your computer breaks again from a family member messing it up, virus attack, or other problem, or even on another computer you may own, you can then learn how to fix it yourself. You know the old motto:
"give a fish to a man, feed him for a day; teach a man to fish and you feed him for a lifetime!! The number 1 thing you also need is Patience!
You should know than unless you've done this type of troubleshooting before or have considerable computer skills, it's gonna take you from 2-3 days to 1 week just to go through the Guide and run all the tests to identify the problem. That may or may not produce a positive result, for if you find that you have a failed hard drive in your computer and the computer is a laptop, you may not be able to replace it yourself, and may have to pay money to a repair tech or shop to do that, and then you can apply a software fix listed in my Guide such as reinstalling W7 from scratch. If you have a laptop that's easy to do that on with an accessible hard drive cover panel, it only takes 20 min. to fix it, and a few hours to reinstall the Windows OS (W7); but it will still take weeks even months to reinstall all your programs and restore your data from whatever external media you backed it up to prior to starting the T/Shooting process with the Guide.
Now, you have an overview of the process and should you decide to tackle it yourself, you need to feel free to post back any questions you have along the way if you get stuck. And remember, there are no Stupid Questions either! There are hundreds of us here who do this sort of thing for a living and are just chomping at the bit to help you, so Ask! We are here 24x7x365, and we try to answer all questions within 24 hrs. of them being posted. This forum is very responsive which is important when your computer is torn apart and you're going to be rather stressed about whether or not you'll ever get it working again!
Best of luck to you,
