It might just fix your problem. (And save you a lot of money)
That also goes for your router when you're having internet problems!
If that doesn't cure what ails you, come back here and ask for specific help. Don't forget to give us as much information as possible. It's your computer and we aren't mind readers.
One last note of advice. There are some updates that require a total shutdown
of your system and then a restart in order for the changes to drivers to take effect.
