Who ever made your motherboard or computer, you need go to there website and download,chipset driver, Modem driver, Ethernet driver,
sound driver, I don't know the hardware you have on your computer because you did not post it.
Right now the computer is using Windows generic drivers, so somethings
will work, but they might not work up to speed or a good as they can with there own drivers.
When you go to thr website of your computer MFG, or the motherboard,
and look at the model # of your system, it will show what drivers are for your system.
Once you get all the drivers loaded, go to ( my computer ) and right click on it, and in the little window pick properties. Somewhere you will see devise MGR, open it, if you have hardware that is missing a driver there will be a yellow shield telling you its missing.
Now that you have all your drivers,
Open System by clicking the Start button , clicking Control Panel, clicking System and
Maintenance, and then clicking System.
In the left pane, click System
are prompted for an administrator password or confirmation, type the
password or provide confirmation.
To turn on System Protection for a hard disk,
select the check box next to the disk, and then click OK.
To turn off System Protection for a hard disk, clear the check
box next to the disk, and then click OK.
Now the next time you have a problem, use system restore or install, but system restore is faster and does the same thing.
