I'm breadboarding a new system. PS (both 4 and 24pin), CPU, and power button/led/speaker connected to mobo with no memory results in mobo led coming on and a series of beeps (for no memory), but when I add memory there is no single POST beep, no video from onboard video (mobo led still on).
My question is about diagnostics - If I get the 'no memory' audio warning, but then get nothing with memory inserted, what can I rule out as working and what might need replacing? Help please!
And yes, i've read http://www.tomshardware.com/forum/261145-31-read-posting-boot-problems. I have two sticks of memory and four DIMMs, and i've tried each stick in each slot (8 iterations) plus both in the paired slots (two more iterations). Nothing. I've also tried both onboard DVI and VGA video outs, but with no post i'm not expecting this obviously.
Basically brand new setup - all the components are straight off the mobo 'suggested hardware' list, so i'm pretty sure compatibility isn't an issue. but at this point, who knows.
Build:
Mobo: ASUS M4A78-EM (microATX)
CPU: AMD Phenom II x4 995
Memory: G.SKILL 4GB (2 x 2GB) 240-Pin SDRAM DDR2 800 (PC2 6400)
PSU: X-Power 585
