Ok guys, this hurts the ego having to ask this. But I got nowhere else to go.
I made my friend a computer, home made, using an ECS mb and athlon cpu. He left it on all summer while he was gone out of town, and when he came back, it didnt work. Everything powers on, but there is no beeps, no video nothing. fans start up. Thats it. Never gets any further then that. I tried clearing cmos, i tried everything. nothing would work. so i had him buy a pcchips m811 mobo and a new powersupply since i didnt know what it could be. Well now im trying to install that. Nothing. No fans turn on. Nothing happens whatsoever. It's in the same case as the ECS, its using the new powersupply. I checked everything. I put the old board back in, it fires up like it did before w/ the new powersupply. So the case button and the ps work. I checked cmos jumpers, i did everything. Its a brand new board, and i had the factory power it up before shipping. What am i doing wrong?
