FUN! problem which I came across in a board I have! Desktop INTEL 815AAE
combo board! Brand NEW!
Problem: power supply Blew up! Twice!
after it went the first time,Sound died
on the motherboard,the board acted as if the onboard sound card did not exist.
A new sound card fixed the sound problem.A month later,The replacment power supply Blew also!
My theory is the Motherboard 3.3 volt
standby supply was loaded down to the max by a problem on the motherboard causing the power supplyto fry after around a month!
I came to this theory in this way!
when replacing the old power supply I noticed the supply WAS running HOT!yet the Motherboard seemed to be ok!
everything worked fine,Video,Hard drive and Cd …except for the sound!With the
new supply it worked for a month,then died! My local Pc store whom sold me the board said this was impossible,could not happen cause the Supply has SHORT protection!(grin)
What do you think?
I am a Tech also!
