Hi

I have recently purchased an ABit KR71-Raid motherboard, geforce 4400 graphics card, 2*128mb DDR 2100 ram, and an athlon 1900 XP processor.

I get no beeps or POST even wehna ll I have in is processor and powersupply.

I've tried the following:
Changed power supply (300 and 400)
Changed graphics card (pci and agp)
Reseated memory and in different slots.
Sent motherboard back to reseller but it was sent back to me - was told there was nothing wrong with it.

Could it be the processor that is stopping the post and beeps from happening?

The fans spin and LEDS work ok.

The only parts I dont know for sure that dont work are the memory and processor. Since I assume that without the memory in I should get a beep does it mean then it can only be the processor?

look carefully at the cpu core

To start with, the speaker has a good chance of being ok and all but verify that the speaker is working to begin with. Do this externaly (with a couple of wires and a battery test for a click sound with the connector disconnected from the mother board). If speaker is working fine then the core voltage of the CPU is in question. Many CMOSs will automatically detect this but some will allow it to be set manually and the default values may have been changed or incorrect to begin with. The correct voltage should be imprinted on top of the CPU or on the fan that is mounted to the CPU. You may also try a jumper reset of the CMOS on the mother board. And no, the system will NOT give beep codes on most mother boards if RAM is not installed. Just a few things to try...Good luck.
