I have learned the hard way over the years, that if you invest in a GOOD UPS to plug your system into, Surge protect your network line, you will greatly mitigate problems that could pop up.
And by good, I mean APC or even CyberPower PSW.
Not one that was special made for Walmart, Sams or Costco.
In a previous business, I had numerous Dell computers that ran 24/7/365 for over 7 years, without any failures......all properly surge protected, and running on their own APC 1500va UPS. Still running when I had to change them out due to a Point Of Sale software upgrade requirement.
