I'm not an expert and I don't know what is causing your issues. However, I'll throw out a few thoughts:
- Could you have some programs loaded onto your PC that are not compatible with Windows 10 (and may be running in the background)? If there are programs that you suspect are causing the issue, you could try uninstalling them and see if that fixes things.
- Could it be that you don't have the correct drivers installed for some of your hardware? I assume you can check on the Dell website if there are any Windows 10 specific drivers for your PC.
- If you upgraded from Windows 7 or Windows 8.1 I will assume that your PC meets the minimum specs for Windows 10. However, if it is a very old PC (e.g. say has less than 4GB of RAM) maybe you want to think about a new PC or at least upgrading your RAM? That being said, if your PC worked fine with Windows 7 or 8.1 then I would think that it should be fine for Windows 10
The extreme option which should guarantee a solution assuming you don't have a hardware issue (which is the one I would go with if the problem was severe) would be to back up all your data onto an external hard drive and "reset" Windows 10 per the link at the top.
You will lose all your programs if you do this (and possibly all your data that you haven't backed up) so you will need to reinstall them. You can't really back up programs so you will have to know where to download them from or have installation disks for them. When reinstalling programs I would install them one at a time, and check that your system works fine after each program. If you install a program and then have issues, uninstall that program and don't use is. When you reset Windows you have the option to "Keep your files" or to "Remove Everything". Either option should work. If you go with the "Keep your files" option (which will still delete your programs), I would still back up your data just in case. Personally I would go with the "Remove Everything" option because I'm careful about backing up all my files and like to start with a clean slate. The "Keep your files" option should be fine too though and may be safer if you are less confident about having backed up all your data.
In my case, Windows 10 did result in some display driver issues on my laptop (occasional display driver crashes). I have a Samsung laptop and it looked like Samsung decided to stop providing updated display drivers for my laptop so I just had to deal with it.
it is becoming annoying loosing all my work and having to force shut down the computer which is not good for the hard drive... any help or answers to my questions would be greatly appreciated
