I'm trying to help a friend with his computer.
120 G Hard drive,
512M DDR Memeor
Amd xp 2600+ CPU
ECS K7S7AG+ Mainboard
When I push the power button, I get nothing..no beeps, no lights, nothing, nada, zilch.. I have changed out the power supply with two others...one that the fan was running on another computer..the other a brand new one... I changed out the CMOS battery trying one from a working computer.. Still nothing.
I don't know if maybe it is a power switch problem or is the motherboard done- gone... needs to be buried.
When I tried the other power supplies, I only plugged in the main connector to the motherboard and the 4pin connector...I left the hard drive unconnected. Nothing.
How can I be sure it is the motherboard. I checked the capacitors on the board.. All of them are clean, flat on top, except 3 near the main connector. These 3 are just slightly puffed on top..not completely flat like the others...but no brown stuff around the base of them. Tiny bit of brown on top like someone barely touched them with a felt tip pen
appreciate any help you can give me.
have a wonderful evening
