Dimension E510 won't power up, just blinking amber light

Hey all, I have a Dimension E510 P4 Dual core processor, 4 gigs of ram, Antec 500w power supply, Evaga GForce 9800 Vid card, Turtle Beach 7.1 sound card and Win7. I have a previous post on this problem; I unplugged all the power connections and jumpered power on the main connector and tested outputs and all are in specs. I plugged everything back in and it worked.

Now after shutdown I can't get power, just blinking amber light. I checked connections on the board and everything is tight. If i mess with it and unplug everything again, re-jumper and plug it all back in it will work the first or second time. Is this a board problem or power supply? The supply is a year old. Would the battery do this? Help!

Hard to say without trying a seperate power supply. Have you tried cycling the power on the Powersupply between restarts? Most power supplies have a breaker switch on them. If not, just yank the cable.

I jumpered power at the 24 MB connector and it booted up, so is the problem between the power button and MB or the MB??

You could isolate the switch as a problem by disconnecting it internally, hooking up the PSU normally to the motherboard and then shorting the pins for power with a screwdriver or jumper to simulate the switch. If that doesn't work, looks like your motherboard I guess.

I jumpered at the main atx connector...are you referring to the 3 pin connector on the board that comes from the switch?

Yes, the pins the power switch connects to on the motherboard. Not sure why there are three, but yes, shorting two of the three should have the desired effect.

dont short it...its not a problem with the power button. its something else. either the psu or motherboard or (unlikely) the ram.
