I've now replaced the power supply then motherboard and no change, nothing on the monitor, POST won't start. I guess the last thing to change is the front panel controller. This is aggravating as heck. I do get LEDs 3 & 4 on with 1 flashing consitantly now. And I tried memory from another computer. (I now have all drives disconnected and no cards installed.) Should I try a front panel controller or quit now dumping money for a lost cause?

Hello firebird, I'd like to think the new parts are good but can't be sure since I only have the one E510 to put them in. I got exactly the same behavior with each replacement as with the old part. so it would seem neither the PS or motherboard is the problem. If I put in the video card (an ATI Radeon X300 128 MB) I can get the first line of the POST (I believe) "RV370 P/N 113-A62801-106 BIOS" to display before the computer resets. I'm going to put in an old PCI video card and see what happens. I'm not sure but I believe the on-board video is disabled on the motherboard (replacement MB too), but I don't see the same behavior (LED 1 flashes with 3&4 solid, no cycling like when the video card is presesnt) when plugging in the monitor to that connector.
Please let me know of any other ideas.
