My s5000xvn doesn't start.
No beeps, no screen signal, POST LEDS stops at Red-Amber-Red-Off state, corresponding to datasheet it means: "Entered EFI driver execution phase (DXE)".
single Xeon 5060 (tried different one for testing),
approved memory - one dimm configuration (tested 4 different dimms),
no hdd (hotswap case disconnected),
550W PU (also tested 700W),
no other peripherals (even a video adapter).
My system had been working fine for several weeks until i shut it down - in ususal way, without powerloss or smth like that.
All coolers work fine, PSU voltages also seem to be fine after startup, but bios is not loading, i think. If i try to switch on my motherboard without processor or with wrong dimm slot filled, it beeps. So i hope my problem is not some damaged electronics.
I tried to clear CMOS, to force second bios bank boot by jumper - nothing helps.
What else sould i try to do?
Is there an opportunity to update bios somehow in my situation?
