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?
Have you looked at the console logs to see what error messages are spawned immediately before your computer crashes? That is more likely to lead to a solution than randomly replacing drivers.
Also, does the problem occur while Norton is not installed?
