Hello!
I'm having problems with a GA-X58A-UD3R Rev 2.0. It fails to power on,
turning off again after just a second or so - enough time for some of the
LEDs to activate and the GPU/CPU fans to spin a little, but nothing else.
Then a couple of seconds after turning off, it tries to power on again
but with the same result - brief flash of LEDs and fan spin, then turns
off. This cycle repeats until I just turn off the PSU completely.
I should mention that I already have a 2nd board of the same model
obtained much earlier which is running fine, so all subsidiary components
are known to be A-ok, ie. CPU, cooler/fan, RAM, GPU, disk (which is
already installed with Win7/Ult/64 from the earlier board), but here's a
summary:
CPU: XEON E5540
Cooler: TRUE with Scythe SFF21F
GPU: EVGA GTX 460 FTW SSC
RAM: Corsair XMS3 3x2GB DDR3/1600 1.65V (TR3X6G1600C8)
Disk: Seagate Enterprise SATA 750GB (ST3750330NS)
PSU: Thermaltake Toughpower 750W Modular
Media: Sony DVDRW (tested without this connected, no effect)
I've closely examined the board, I can't see any damaged or burned
components. I removed everything and checked the CPU socket, all the pins
look A-ok, none bent or missing, etc.
I tried the usual steps for a BIOS reset (battery removal, power cord,
etc.), nothing worked, though I'm open to suggestions of alternative
procedures.
Any ideas anyone?
If it's of any help, some LEDs are lit long enough each time so that one
can make out their colours, which are:
- The group of three LEDs next to the battery, the one furthest away
from the battery (next to the capacitor), this flashes red twice.
- The group of seven LEDs inbetween the ATX power socket and the last
DIMM socket, four of these LEDs (left to right, ie. the one closest to
the battery first) light up as follows: GREEN, GREEN, ORANGE, ORANGE.
- The group of six LEDs to the right of the ATX power connector (just
above where the word 'DDR3' is stenciled on the mbd), these all light
up as follows (left to right, ie. the one closest to the ATX connector
first): GREEN, GREEN, ORANGE, ORANGE, RED, RED.
Don't know if that conveys anything useful, but just thought I'd mention.
I recorded a short movie showing this power cycling effect (approx. 8MB):

Sony dig camera (I suggest turning off any audio, it never seems to
record sound that well).
Thanks!!
