Others may disagree but I believe the first place to check for updated drivers
is at the computer manufacturer's website. (If it's a home built machine then check the individual manufacturer websites for motherboard, graphics card, etc.) I also think most people would say "if it ain't broke, don't fix it."
A few months ago Windows Updates said there was a new driver
available for my Sony Vaio's Intel HD 3000 graphics. I went to the Intel site to verify. It was there so I installed it. Almost immediately I began getting blue screens. I went back to the older version and all was well. I emailed Intel and they said once they release a driver, each computer manufacturer or component manufacturer is free to optimize the driver for their particular needs. Sony hadn't optimized it and it wasn't compatible with my Vaio.
If you decide to install those drivers I'd recommend you make a restore point just in case something doesn't work. Better yet, a system image. Go to the Acer website to verify the version being offered as an optionl update is the latest and greatest for your computer. Same thing with nVidia.
