    Hello! This is my first post...

    I was experiencing the same problem: Gigabyte UD5 wouldn't post, same Phase LED lights. Just yesterrday I RMA'ed the mobo to Newegg.

    My concern is now the PSU, since it seems like it is a potential culprit. I have a newly bought Corsair 850TX, which is similar to the 650TX, and I didn't notice any 8x2 12v connection. Did you mean the 24pin? Unfortunately I do not have a separate system to test the PSU with (this i7 would be my only computer).

    In any case, I had plugged in both the 24pin and the 4x2 pin and was still running into the boot/no display/phase LED problem described in the OP. Do you or anyone suspect this is a PSU problem?

    I forgot to mention:

    Memory is OCZ 1600 6gb

    I tried seating each module one at a time, only on the white slots (the outside 2 slots were the ones I were using when seating 1 at a time).

    I also started from scratch, reseated the CPU (no bent pins). Which is why I am led to believe this is either a PSU or a mobo issue. Unfortunately no other system to test the PSU ..

    Yep, he's wrong, he mentioned the 2x4 pins 12v.

    Make a test with another PSU first, its possible...

    directoryman, did you get anywhere yet?

    I would not suspect a PSU issue, but very well could be a DOA one maybe? Can you test either in another setup or with a PSU Tester?

    Ya, I think that user may have been trying to connect a 8Pin GFX card cable to his 2x4 ATX 12V motherboard connection or ya he was confused and meant the 24pin, not sure

    You need to connect the 8 Pin ATX 12v (4x2) and the 24 pin of course

    If not you should start with things outside of the case, off the motherboard tray to eliminate shorts as a issue. Then remove all hardware except the GFX Card and CPU/Heatsink and your ram. Nothing else, then see if it will start. If not try clearing the CMOS using the button for one minute with the PSU unplugged from the wall. If no luck, try clearing the CMOS using the method I posted in post #2 here >>>

    Hi everyone.

    I am getting exactly this same problem with my board.
    Have read the posts and will see how I do!

    Stupid computer! Even with all the RAM removed and CMOS reset, it still shows those same LEDs. Something is definately wrong!

    Pal;


    My problem was in the PSU, not the board or another peace...

    I bought a Corsair HX1000 and all went fine.

    Hi everyone.

    I emailed Gigabyte and got this response....

    Hi,

    Please trouble shoot one more time there are many things can cause system not boots up, here is the trouble shoot procedure :

    Remove the board out of the chassis/case and test on bench.

    Please make sure 4/8pin 12v connector and MB 20/24 pin connector are both plugged; just install cpu , video card , single stick memory ( on slot 1 which is close to cpu ) and pc speaker ,turn system on if no video display comes up check error beep code :

    -one long continue beep, it means memory can't pass bios check, try re-install memory or try other brand name memory,

    - 3 beeps or 2 long and 8 short beeps then 2 then 1, it means video card can't pass bios check, try re-install video card firmly or try other video card

    - no beep at all, try remove the memory with out memory turn system on check if any beeping signal ,

    -without memory still no beeping signal symptom tells either motherboard or cpu is defective, test cpu in other system or test with an other known good cpu to confirm defective motherboard.


    I have tried this and had a bit of luck, see my response below...

    Hi

    Thank you very much for the reply. I have undertaken the instructions below as you mention and have (after a lot of also trying other things) managed to get the motherboard started twice.


    The first time I had the computer working with the barebones, slowly built it up with all RAM and connections etc. It still worked. I then moved it back to its normal home, unplugged the DVI monitor, connected the HDMI TV (my normal screen) (note computer was off) and then tried to start again. It went back to fail/not booting as described before.

    I then tried again. Stripped it down, eventually managed to get it started, built it up (with DVI screen) and turned it on - fine.
    With the computer on, I plugged in the HDMI TV - Fine (and re-booted fine)
    Then with computer on, I removed the DVI monitor - fine - just the HDMI TV showing the picture.
    Tried to reboot (with just HDMI connected) - back to fail/no boot as before.

    The only way to get life back in to it is to stip it down as I have done a few times now. Does this mean I have a faulty Graphics card (its a Palit 9500GT with VGA, DVI & HDMI) or do you think it may be the motherboard?

    Many thanks

    Nigel
