Re: After Lightening Storm - Computer Will Not Turn on



agreed....
Hundreds of dollars of tech time to change a $40 power supply.

but i still want to know how best to isolate if a MB or cpu is bad.
Ben's rules for troubleshooting are standard and spot on,
but it stops short.
I know there is no good way other than to swap them out. and in the field, i'm not about to take a working computer apart to swap a cpu.
and i dont have spare cpu's and mb's around for testing, so its usually not cost effective to fix them at that point.
i get to that point and i offer my clients a tradein allowance for a new computer. works every time.
so if anyone does know any easy way to tell, i'm all ears.

i agree.
but how will a voltmeter tell if you have a bad motherboard or a bad cpu?
everything else is easy.




Ask w_tom. He has ALL the answers. And apparently a whole lot of unused time to repair a failed system.

Working in a failure analysis lab his methodology is fine given ample amounts of time.

Here in reality, a system is down and it needs to be turned around ASAP - especially for business clients - and they don't give a flying shiite how you get it fixed except fast and right - the first time.

One dissertation about whole house grounding and that'll be a lost client.
