i,
This PC is 6-1/2 yrs. old, so there are several possibilities; virus/malware attack, failing/failed hardware such as hard drive or RAM memory stick(s), or Windows registry corruption. Since kemical's suggestion didn't work, those are the most likely possibilities.
Prior to starting any software troubleshooting or hardware testing, it's always best to
FIRST BACKUP ALL OF YOUR PERSONAL DATA TO EXTERNAL MEDIA! THIS WOULD INCLUDE YOUR LIBRARY FOLDERS FOR DOCUMENTS, PHOTOS, MUSIC, VIDEOS, AND ANY SAVED E-MAILS OR ATTACHMENTS IN ORDER TO AVOID IRRETRIEVAL DATA LOSS!!
First thing you should do is to scan your PC for viruses and spyware viruses using whatever your built in AV program is (also make sure it's up to date and actively running). Scan/remove all viruses found. You mentioned Malwarebytes and that's the best scanner to check for spyware viruses. Repeat the procedure of scanning/removing all spyware viruses found with your MBAM. Reboot your computer. If the error messages you were getting go away and your Internet comes back, you simply had a spyware virus which attacked your PC and disabled your network adapter driver.

This is so common these days as to be ubiquitous. We see 50-100 of these viruses taking out user's Internet connectivity a month!

If the error messages abate and your Internet comes back; you're fixed and all set to go!
If your problems persist, continue reading below:
You mentioned you were using
Acronis for your backup image file, and that's fine. It's one of the 3 backup image files we regularly recommend here; the other 2 being
Macrium and
EASEus TODO; all 3 of these programs we've testing rigorously from WinXP-W10. So you are good there. However, I would also recommend a manual folder/file backup using either Windows Explorer or if you're not familiar with this tool already built into your Windows7, I suggest you download the free
AOEMI Backupper, the easiest way to achieve a folder/file backup to external media. This program does
NOT backup your programs, as Acronis does, but only your data; such as that contained within your Library folders as above.
I could just tell you to do a Windows7 reset and that would be the end of my Post. However, since your computer is nearing 7 years old, it's highly likely it's developed hardware failures, and doing a Windows reset or reinstallation is a complete waste of time if your hard drive or memory sticks have failed.
No software on the planet can fix Broken hardware!!
If you're never replaced the hard drive in that PC, it's highly likely that it's failing or has already failed and these are the real reasons for your hardware errors showing up in Windows. So you know, modern hard drives made for computers made in 2009 or later are only designed to last 3 years!

This being the case, it makes sense to test your hard drive and RAM memory sticks; if they report any errors, they have failed and must be replaced.

By now, I'm sure you'll see why; as if you don't and you go to all the trouble of reinstalling your Windows7, the failures will continue since they are being cause by failed hardware and not software or drivers.
I wrote a handy little free
TROUBLESHOOTING GUIDE available here that will provide you with step-by-step troubleshooting and software repair procedures:
Windows 10 - Unclickable Task Bar.
Once your hardware testing is complete, and no errors from your hard drive or memory sticks are found, you can continue with the Software repairs section of the Guide. If either tests return errors, you'll have to replace your hard drive and any failed memory sticks until you can pass tests on both without errors. Once you do this, you can begin applying software solutions. Once your hardware is known good; you can fix your Windows with more aggressive repairs in my Guide.
This is a lot to take in, and repairing one's own PC is not for everyone.

You need much patience to do this, especially if you've never attempted a complex repair such as this. The Guide is 6-8 pages and is quite lengthy, so I suggest you print it out on another working computer that can get the Internet and keep in front of you while you try and fix the broken computer (the HP). The hardware testing process can take several days. If you don't have this kind of time, or don't have the patience I mentioned you need, or just can't wrap your head around this entire process, I urge you to consider taking it to your local licensed Computer Pro and paying him to do all this tedious work for you!
If you decide to attempt this yourself, feel free to post back any questions you have to this thread and we will try to answer you within 24 hrs. Most other tech forums on the Internet are not nearly as responsive as we are. And we are here 24x7x365 to support you!
Best of luck to you,
