KR7A-RAID constant reset; bad MB?

[Rebus]

I have a KR7A-RAID v1.0 machine that suddenly won't even POST. It was running fine until found dead and wouldn't reboot. I've swapped RAM, power supply, AGP video card, CPU, pulled all the PCI cards, cleared CMOS -- no change. Lights come on but the screen stays blank. The HD's spin up but aren't accessed. Of interest, the three LED's on the MB behave as follows when the power switch is activated:

D14 5+V = On
D16 Power On = On
D17 Reset = On

I don't think the D17 Reset LED should be on continuously. I disconnected the reset switch from the Motherboard connector with no change, so it's not a bad switch. Any other ideas as to what would cause a constant reset?

try a pci video card,to rule out the agp slot.

No change with an empty AGP slot. The CPU reset line is still continuously active when powered up.

HI,
If the Reset led is on you have a problem with the reset line,I would check the MB,like underneath to see if you slipped a scew or something is shorting the reset line,baring that,it sounds like a bad gate(the switch that activates the LED and RS line!) you would need to return the board for a replacement! if it is within 3 years of when it was made or 1 year depending on which is longer(grin) you will get a new one! run it through the Rma online! the $25 charge is for out of warranty boards!

Cheers Dennis
