Just a suggestion if you need it.
I was using Google Chrome as a browser and it became every slow.
I tried everything I could think of to get my computer back up to speed, all to no avail. All the while I was assuming it was the computer that was not operating properly.
I then tried using Mozilla Firefox as an alternative. The change in speed was remarkable and is now probably faster then I had before.
If you are experiencing the same problem; don’t get your sledge hammer out and do a number on your computer; just Google Mozilla Firefox and download, it is free and can’t hurt. This suggestion may save you some aggravation and lot of soldi.
