Rig has been running fine for a year.
Not over-clocked at the moment.
Has latest BIOS
This morning I powered down the rig.....then did a cold re-boot.
Rig will power up....mobo lights up...But I have no beeps, no BIOS...nothing.
Stalled or something?

I then did this:
CMOS clear...Same result
Battery pull..same result
Did a bare bones boot. ( CPU, Video, 1 DDR2 stick) Same result
Tried a different C2D CPU....Same results
Tried different video card..Also tried video card in slot #2...Both same results.
Tried a different PSU..Same results..

I'm at wits end here.
Bad mobo??? :fou: 

Man.....I'm sick of shelling out cash for components that last a little over year. :fou:

Welcome to the party of unexpected Gigabyte failures...

Consider yourself lucky, my GA-965P-DS3 did this 3 times in less than 16 months... to be clear, I built the same computer 4 times and ended up purchasing an Asus motherboard.

Well this is odd:

I did another bare bones boot try using one memory stick just to narrow down if it was my G-Skill sticks.
Sure enough...I was able to get the rig to boot using one stick.
The other 3 sticks I have would not boot.
I tired the "good" stick in all 4 mem slots and the rig would bot up fine.

So you mean to tell me that I somehow have not one....but 3 bad sticks of the same memory, brand, and purchase date?

What do you think happend here?
Can the mobo kill 3 sticks of memory without any known reason?
I wasn't even over-clocking.

Try doing a 'Load Optimized Defaults' with the working stick; save, exit, reboot; shut down and add another... RAM P/N? I have an X48 in my workstation, with 8G of G.Skill F2-8500CL5D; have run it @ over rated speed, both a tenth under and over rated voltage - takes a lickin' and keeps on tickin'(but I have a fan on it...) - and a sizeable number of people here have had really good luck with it; be very surprising if it died with no cause! One more question - have you recently added a new (or, more often, old) USB device - occasionally they will cause devilishly weird symptoms, and 'break' the CMOS settings...

BillBat:

The only change I've done in the past 2 weeks is installed Win7 x64.
No dual boot....no overclocking.
Plain n simple set up.
Latest BIOS or the mobo from Giga flashed a year ago.
Rig has been running pretty good.
No other hardware or new USB devices were addded.

I'll try your Load Optimization method though.

thanks

Thought of another question - to run four DIMMs, you typically have to have 'bumped' your MCH voltage by a tenth to 1.2V - have you done this? Might try it, could fix all (though I can't imagine why single sticks would fail, unless CMOS got screwed somehow...)

Tried the Load Optimization in CMOS and had the same effect.
Still only one of these G-Skill sticks that work.

The sticks are running at stock voltages.
No tweaking what so ever.

Update:
I borrowed some DDR2 sticks from a friend and popped them in....4 x 2GB sticks.
Rig booted like a champ. Shows all 8GB in BIOS.

I have to think its the bad 3 sticks.
Perplexed as to why 3 of them got wasted though.
