Suggestions on finding out if dead motherboard (MB)or dead powersupply (PS)?
As soon as 120v is plugged into PS case HDD & Power led flicker nonstop, MB fan runs but nothing else works. Owner was having problems getting puter to boot off and on prior to this. She went ot turn it on and all she get is the flicker.
Have already tried:
1. removing power & ribbon cables to drives, flicker the same.
2. only external card is modem, removed it, flicker the same.
3. removed power switch connecor to MB, fliker the same.
MB: imperial 134841 (I understand is a common MB used)
thanks in advance
