What are some of the signs you are looking for?
Driver Booster 3.2 and Smart Defrag 4 were previously on this PC. However, I removed them a few month ago.
Here is how I implemented your suggestion...
First, I found Smart Defrag 4 (Not an easy task mind you since I cannot access www.iobit.com for some unknown reason.), downloaded it, installed it, and uninstalled it.
Second, Since I could not find Driver Booster 3.2, although I did not look very hard, I found Driver Booster 3.5 on download.cent.com and downloaded it, installed it, and uninstalled it.
I hope the steps above did no harm!
I will be performing the steps above and below as soon as I finish dinner.
... and that is exactly what I will do later this evening!
Thanks again for everything you are doing for me!!!
