G'day Mates,
Summary of Problem: Switch activates power supply, fans come on intermittently but usually shut off. Sometimes fans continue to run (?slower) but no BOOT up occurs. Have suspected switch failure but not sure. Switch turns on and turns machine off. Power is going through switch but not sure about whether it is continuing to make contact internally.
Live in Really RURAL area on Farm. Grid power failures are common. Problems started after most recent Grid power failure
Equipment:
I have a relatively old eMachines.
Model ET1331G 07w
AMD Athlon II X2 250u Dual-Core Processor
NVIDIA GeForce 6150 SE Integrated
640 GB HDD
4GB DDR2 memory
Mulit-in-one Digital Media Manager
Windows 7 OS
PSU: FSP 300-60EP(1)
Power supply 24 pin connector

Test results with Multimeter
Connectors #23-#24: 4.77 vDC Expected = (5 v +/- 4%) 4.8-5.2)
#14-24: 10.77 vDC Expected = 12 v =/- 4% (11.52-12.48)
Based on multimeter results am assuming PSU is the problem since measured voltages below standards.
QUESTION:
1. Should I expect replacing PSU will resolve the problem?
2. Should I pursue the question of the switch or just replace PSU and see what happens?
NB. (I’m 71 and retired. This is my first attempt to do surgery on a computer. In my other life, I did some birthin’ babies, flight physicals, etc.)
Any specific suggestions (other than “go fly a kite") will be most graciously appreciated.
