Hi, I have a "late 2012" iMac running Yosemite version 10.10.3. The machine has a 3 TB hard drive, most of which is not in use, 32 GB of RAM, a 3.4 GHz Intel Core i7 processor and a NVIDIA GeForce GTX 680MX 2048MB video card. As you can see, this is not a bottom of the line machine. Its rather hefty.
For the first couple of years, I was on cloud 9. I loved my iMac, which gave me ZERO problems - now, not so much!
Ever since I installed Yosemite I've been experiencing issue. The most recent and problematic of which is the reason for this post. -- Every time I visit sites like Zillow.com or eBay.com or anything with intense web images, my machine reboots on its own, shortly after leaving the site.
I've uninstalled Norton 360 and reinstalled a fresh version from the Norton site. I've run the Apple hardware system tests multiple times in both standard (about 5 minutes) and extended mode (over 2 hours) and each time I get -- "no problems found." I've rebooted and done it again and again and still nothing on the hardware side.
So, I wanted to upgrade my NVIDIA GeForce GTX 680MX video driver, just in case it might have become corrupt. - I went to the NVIDIA web site and found a new driver (WebDriver-346.01.02f01), which NVIDIA states its for Yosemite 10.10.3. However, when I try to install it, I get the following error message:
Computer not supported
This computer is not compatible with the NVIDIA Web Driver.
The installer closes down thereafter.
OK, so what am I doing wrong? How do I update my NVIDIA driver to the latest version to work with Yosemite?
