PC Build Steps

Ok just because I like steps i am going to create some steps. Please give me the stamp of approval/disapproval

• Install system in case
  • Remember to connect SSD and optical to same SATA ports on motherboard
• Turn on PC
• setup HDD
• run blend test in prime95 for 30-60 min
  • run realtemp at the same time

• While in Prime95 test
  • if CPU goes above 70c in RealTemp, I have a leaky CPU
  • if my system locks up or blue screens, there is an instability in the system somewhere
  • if my system does not lock up or blue screen, my CPU is not damaged and I am in the clear!

What do you guys think??

 

2 laptops suddenly cannot log onto wifi.

Have 2 Win-10 laptops that were doing fine - Nighthawk R700P set up many months ago. Suddenly both cannot log onto wifi. Going to list of available networks, choosing "home" and disconnecting and then reconnect does not help. Suggestions? Not the greatest computer wizards here.

Lenovo laptop wanted latest Windows update; upon rebooting everything seems fine. Other machine is actually an HP all-o\in-one, not actual laptop - but Win10 anyway. Will check if update is needed.

Now HP is OK as well. Problem began there yesterday and on Lenovo today but now both seem OK. Curiouser & curiouser as Alice said; sorry to have taken up your time.
