New Intel h55hc motherboard, 2 new sticks Kingston 1 gig each installed as 2 channel, i5 650 processor, on board video & audio, no PCI or express cards installed, PS voltages measured at 5V and 12 v, fans start, stop after few seconds and recycle, no access to CMOS, removed battery waited 15 min, reinstall battery - no luck, checked power plugs for proper insertion - OK, removed one stick, substituted 2nd stick - no luck, remounted processor still nothing. Is it RAM, motherboard, or processor? I'm frustrated
The motherboard has been breadboarded. The only connections are to the power supply, video cable, mouse, keyboard and connection to front panel power switch. When the 110v is applied and the power switch activated the fans began but do not come up to full speed and then stop, they continue the on-off cycle, no video signal
I allowed the continuous on-off cycle to continue after 10 minutes it stopped and the fans began to spin at proper speed and I began to get three beeps indicating RAM problem. I have removed the RAM, installed one stick at a time, interchanged sticks, tried new RAM from a different manufacturer, interchanging sticks - still three beeps. Removed the CPU, rear fan cycles but no beeps.
