Thanks for your very quick response! I've updated the network card
drivers using the link you provided. Once the drivers were installed and rebooted to confirm they "took" (just checked the version and date of
driver), I couldn't get online. I power cycled my router and now I'm back online.
Yesterday, I ran Memtest for about 6 hrs with no fails.
I'm running Prime95 stress test now and will report the results.
From the info I provided in the attachment, were ALL critical errors related to the network card only? This computer worked totally fine for months with no issues with the same driver.
Thanks again!
