At the time I was able to find parts at an electronic store, (first in Dallas), an installed switches as required, memory upgrades and gulp a floppy drive!
My computer is on all the time and whenever an update arrives it will restart. Make sure your PC has a condom, (Norton) and surge protector. They do work despite what OBummer says!
I have had three PC’s and turned them all off at night. I have never had a problem with any of the three, They have all been Dell’s. I don’t want any updates running on my machine unless I know what it is. I spent 30 years in DP and that is a little habit I picked up from that time. If an update is going to cause problems I want to know about the update. I keep my PC’s 3-4 years before getting new ones.
