Motherboard problems?

By kettels ·
I'm building an Athalon 1.3 system using PC2100 DDR. First tried ASUS A7M266 mobo, then two different Gigabyte GA-7DX mobos. None of them will display more than 1 or 2 POST codes before halting. Did I receive 3 bad boards in a row? What DOA rate should I expect?

Motherboard problems?

by Some Guy in Seattle In reply to Motherboard problems?

Interesting problem! Are you using the same CPU on all boards? May be a problem there. How about the RAM? Make sure it is the correct speed for your board (133 in 100 should work fine, but 66 or 100 in 133 won't). Does it give any beeps during POST? The motherboard manual or website should have the key to deciphering what the beeps mean, if so. Can you jump into the BIOS menu before the POST dies? You might find some specific settings there too (a long shot since you say you have used different motherboards).

Since this problem is occurring with different motherboards I suggest focusing on any common parts that you are swapping between the boards.

Hope that helps,

configure first the cmos jumper clear the cmos for a few seconds to clear settings that are not compatible to your components connected in the motherboard. then restore jumper to normal setting.configure your settings when your computer restarts.

It is very rare to find one board of either of these brands defective, three is highly unlikely. The GA-7DX does support PC21000 DDR so you're OK there, but make sure any and all jumper settings are correct for your configuration. Try different RAM sticks. And ALWAYS mount the fan to the CPU before you apply power. Failure to mount a fan will give you just the same results as you are experiancing (at least the first time)

Glad to know the reliability of these boards.
