Here is the system - GA-7N400pro2 Rev 2.0 MB, 2x512 PC3200 ram, XP3000 processor. 480Watt Antec true power, Tower case, many fans.
Problem is, it won't boot any more. When I try to start it up all of the fans except the CPU fan turn on. After a few seconds it all shuts down. The CPU fan works fine when connected elsewhere. The CPU is not hot. The system is not overclocked. The system did not overheat (Bios monitor as well as external monitoring).
I have tried two different power supplies. I started checking the voltages with a meter, so far they look ok. I pulled the board from the case, stripped it down to nothing, also tried it with CPU - 1 RAM - and Video with the same result. watching with the meter hooked up, the 12 volt connector for the CPU fan never comes on. Last thing I tried was to use and adapter cable (came with my case I beleive) to power the fan, but also connects the fan speed cable back to the MB. Same result.
Help please
