|When you disable and enable system restore it resets it. You will not have ANY restore points but they should start working after that. If you don't have enough empty space to save a restore point it won't work. |
Check in My Compute to see total partition size and free space. Run Windows disk cleanup or download Ccleaner Slim to cleanup you unneeded temp files and cookies. Get Ccleaner Slim at the link below.
After cleaning up the files go to manage> storage> disk management. Run Analyse to see if you partition needs to be defragged.
Create a restore point and then install the drivers that you downloaded and transferred to that computer via disk or flash drive, whatever.
