Why do so many techs skip checking the power supply first?
I've been doing house calls in Phoenix for about 2 years now, and I'd say 8 out of 10 machines brought in for 'not turning on' just have a dead or failing power supply. The other day a guy spent 45 minutes reseating RAM and swapping cables before I checked his PSU with a tester and it was dead on the 12V rail. Am I crazy for thinking a quick PSU test should be step one every time?
