It does the same thing with RAM. Not trying to get it to boot, just power on and accept power. If I can get it that far, I'll install 1 stick RAM and video card & just try to see BIOS... (baby steps)
there is no beep. The light flashes and the spkr clicks about 4x/sec (sync) - looks like a power oscillation indicating something's not right - just can't determine if MB or CPU is causing the oscillation.
If CPU removed or 12v 2x2 disconnected (still no RAM), the light is steady green and all fans/PS run normally and spkr is silent.
Either MB or CPU is bad - which?
