Is it possible you could strip it down just to bare components (mobo,
cpu, mem, g/fx and power supply on a desk? No case required. Plug it
all together and then short across the 2 power pins to see if starts up.
I believe mobo needs to sit on something insulated also. Others here
could expand on this.
A piece of corrigated cardboard like cardboard boxes are made from works
just fine.
oh well...........
This should rule out any kind of shorting out on the case that is
preventing it booting. Also, just as an afterthought, is the clear cmos
jumper set correctly?
Stripped the system entirely, placed the MoBo on a Phone book, installed
processor and processor fan ONLY with NO RAM, no cards, no drives.
Plugged in the main power connector to the board and the 2x2 connector
for the processor and then shorted across the power pins and SAME
result, powers up bu NO POST beeps or anything else!!!
