My system starts up, but about .5 seconds after it turning on, goes straight into sleep mode: the fans all stop spinning, and the power led starts blinking. There is no display on the monitor, and the same thing happens w/o a video card. I found a thread on anandtech about keyboard problems, but I've tried about 3 keyboards, both USB and PS2, and it still has the same problem.
I have a new processor in the system too, as well as a new PSU. Mobo was rma'ed due to not starting up at all, and is a new one of the same model.
I've tried two different power supplies.
The system turns on propertly without a processor/with the 12v rail unplugged, but as the processor is new I dont think it is the problem, and I dont have another system to test it on .
Are u experienced in building systems?
1-Did you plug in the extra 4 pin power connector to the motherboard?
2-Did you plug in the extra power to the graphics card?
3-Reset the Bios?
4-Try one stick of memory in the proper slot?
1-Did you plug in the extra 4 pin power connector to the motherboard?-Yes, ive checked and rechecked it. The funny part is that if it isnt connected, the fans all spin up and stay on, but it obviously doesnt post.
2-Did you plug in the extra power to the graphics card?-Yes, it even happens w/o the graphics card
3-Reset the Bios?-yup
4-Try one stick of memory in the proper slot?-I've tried it with no sticks, and it still happens.
something is grounded in your case and the PSU protection kicks in to protect the whole thing. take the board out and check for anything underneath the board making contact with it, apart from the standoff you use to screw it there. Maybe you put one too many standoff that has no hole for it.
