Situation similar but not exact to Gullyfoyle several posts down. The board is an XFX nForce 780i SLI. You can see the rest of the machine specs in the signature. The machine locked up with a bsod one day, rebooted it but it wouldn't get thru the the nvmemory test, which is the second of two memory tests it performs. After hanging there part way thru it eventually offered the option to cancel the test. Once canceled, post continues, displaying the cpu info, but it does this very slowly, one character every couple seconds, and then hangs again. This repeated thru a couple of resets. At this point I decided to pull the plug for the standard count to 10, and replug. This resulted in a totally dead machine. Not a peep nor a fan. The post code 2 diigt readout is dead. The only sign of life is the little blue LED on the board which is typically steady lit when the unit is plugged in, on or off. This is now blinking.
A search of the symptoms and that little LED brought nothing. A note to XFX got me "Any LEDs on the board are not for diagnostic purposes, only to show the flow of power". It was steady, now it blinks, hmmm....
Anyway. tested the power supply, tester says it's good. Swapped it out with another one, a spiffy new one awaiting another build, same thing, ie, nothing. Pulled the cards, pulled the memory, nothing. disconnected all power connectors but the mobo, nothing. The only thing I havn't pulled is the cpu, because I wan't mentally prepared to disrupt the water cooling at this point. I know I know, if the board or chip is bad it's gotta go anyway. Will a bad cpu make a good board act dead? This is something Ive never run into before.
Grateful for any thoughts on the matter, Thanks, ZZ03
