Cant get my computer to start

[Feskar]

I'm building a machine for a friend, but I cant get it to start. Its a asus a7n266-vm mb. When I plug in the cord, its a green light on the board, but nothing happens. I suspect in can be some jumpers that arent correctly set, but I've tried many combinations. Anyone got an idea whats wrong?

Take a look at your case to mobo cables (LED, Power on, HD LED, reset, etc.) and make sure you have them plugged in correctly. If you're getting power to the board and press the power on button on the front of the case, it's possible that those afformentioned's aren't arranged right.

I've tried that too, in all directions. Even tried only the power-switch cable. None of it helped

You could also try clearing the CMOS
There should be a jumper on the board (usually near the BIOS chip)
Pull that jumper off the two pins it is on and shift it over for 30 seconds or so w/ the PC off - then put it back to where it was and try to turn the PC on

My next guess would be the CPU. Carefully remove it and reinsert it again, making sure it's fully seated. Then be even more certain that your HSF is remounted flushly. I'm thinking the CPU is not inserted all the way. If that doesn't fix the problem. Remove every extra PCI card not needed to run the machine. Leave only the video card (or better yet use the on-board video), the RAM and the CPU. Also make sure each of those are fully inserted, if it don't fire up then you have bigger trouble than I thought.

Now I've tried clearing cmos and tried another cpu. Nothing helped

Have you tried removing and disconnecting everything except the vid card? I had the exact same problem when I first built my new box and it ended up being my PCI IDE Raid controller wasn't seated properly. Reseat the CPU, RAM and Vid Card. Make sure the Power button is plugged into the SoftPwr connector on the motherboard.

check out simple things, like voltage(110v or 220v) & on/off switch on the power.
