Abit BD7M problems (no bootup)

[demoniac]

I just wanted to get some opinions here. We recently purchased an ABit BD7-M, 256MB PC2100 ddr ram, and a P4 1.6GHz cpu (sock 478).

I installed everything, as normal, and it wouldn't do anything. Well we had another motherboard of the same so we tried it, no luck. Tried different video cards, RAM, power supplies, and motherboards to no avail. The only thing we didn't have a 2nd of is the CPU. (by the way, the P/S is P4 compatible)

So then on the last try on one of the motherboards I turned it on and heard a SNAP! and got the familiar burnt electronics smell. It burned up the chipset under the large heatsink next to the cpu (northbridge?).

The weird thing is the motherboard has 4 lights, one for power, reset, HD, and something else. Anyways the reset light always stays on, on both motherboards. Manual says it should only come on when you reset the machine.

Not sure, but we don't get the 2nd cpu until monday. Would a bad CPU cause all this? We received no beeps from the speaker and the cpu didn't get hot like they normally do when they're broke. I don't know, it's got me stumped.

Any input would be great

Thanks,

donno if you checked but the clear cmos jumper could be in clear cmos setting you may need to put it to normal...

Thanks for answering But first thing I did was clear the cmos and reset it back to the normal jumper setting...

thanks though

are you sure you are connecting the reset wires correctly if you got the wires backwards or something...
it is probably your cpu.... and the pop noise didnt sound good. you got the correct cpu voltage? and speeds? and correct memory and speeds...
the chip that fried was your chipset which comes after the front side bus from the cpu and before the ram, and back side bus.


so I guess it could have to do with ram type but doubtful, really it is probably the cpu, which caused the chipset to fail... or something lets see what that other cpu does, if it works this one is bad, and they should pay for it blowing that mobo..
