    Default UD5 Boots then turns off

    Hi yo,

    I've been scrambling the internet for hours trying to figure this out. I have a new build consisting of:

    i7 920
    gigabyte ud5
    6gb ocz 7-7-7-24 ram
    geforce 8400gs * old but working
    13gb seagate hd * old but working (yes, 13gb)
    noctua cpu fan
    corsair tx750w psu

    Hi, I'm currently building an I7 PC, and I'm having trouble booting the Motherboard. All my parts are new except for the Hard Drive and video card, though work just fine. The problem started when I was trying to boot up the mobo for the first time, it would turn on for a split second then turn off. I would try for 3 more times with the same results. On the 5th try, it would then go through the boot cycle just fine. It would try to look for a boot device, and it didn't find it, so it shutdown. When I try to boot it back up, it would light up the leds, all the fans would spin, and then it would shut down. Every time I try to do it, it would do that. If I get lucky, it will turn on and POST. So the problem is that it doesn't always turn on. The Power supply is a brand new Corsair 750w, and I have both the main power plugged in as well as the 2x4 plug near the cpu. As for the memory, it would do the same even if I take out all the ram, or have 1 stick in the 2nd slot, or the 4th or 6th slot. I tried all the slots, but the problem is the same. Mobo doesn't boot up all the time, maybe 1/10 tries, it will boot and post. I figure it was a bios problem, so I flashed to the latest F7 Bios, after update, I reboot, but it would shut down instead. When I finally got it to boot, I go into CMOS and choose "optimize settings", shut down, have a difficult time to boot up again. When it does boot up again, I'm able to boot xp cd on a usb cd-rom drive, and I tried to install XP, it goes through the 1st phase, and half way, it blue screens with error x000007B (even on a reformated NTFS drive). When it does boot, it stays on just fine. I'm not sure what the problem is. This isn't my first custom build, and I'm sure I know what I'm doing. I recently built a pc with an EVGA board, and everything worked fine. So I'm not sure what's going on...

    side note: I just read a review on newegg for the same psu as mine with similar symptoms so I'm hoping it is the psu. I"m going to have to test it with another psu if I can find one...

    Hello! this sounds very similar to my issue and although I haven't resolved it yet, it seems switching the power supply off as well vs. just hitting the button will reduce your time waiting for it to boot properly.

    Also, I have all the cpu bios settings disabled except for turbo boost and hyper threading, and I feel that this has reduced the frequency of this issue. (Although this may just be in my head)

    Your bsod though may be unrelated, have you tested the hdd for bad sectors? I never trust the windows utility, i personally use HDTune. If you dont have it I would go download UBCD4Win it has HDTune and Memtest, both of which you should run just to further test your system.

    Your problem is probably due to some of your bios settings.

    Check out this thread and post your bios settings using the bios template in the 2nd post.

    Did you load OPTIMIZED settings before you made any bios changes?

    Hi guys, just a little update: I noticed something strange last night. I had my HD(maxtor) power unplugged and I tried to boot, several tries (10+) with no results, then I plugged in the power cable only (no ide cable) into the HD and what do you know? It booted right up. It doesn't always boot right up, but it has a higher probability of booting up, maybe 3/5 tries when I do. I was able to boot up a memtest and ran that for 8 hrs last night, and the memory passed, so I know it's not that. I'm leaning more towards a PSU issue here...but i'll have to check tonight.

    @ghost_deini: Yeah, it's weird. Did I mention that the HD is IDE? Could that be the problem? I also read somewhere that it could be xp with my video card, because I've had some issues with it before on another computer that wouldn't display during bootup, but only during xp loading...As for the HD, I tried 2 different HDs, the first actually was bad, the 2nd was formatted, but I'll have to try a Sata drive when I get the chance. I'm going to see if installing Vista would alleviate the problem too.

    I don't remember if I loaded optimized settings. But I loaded it AFTER I updated the bios, but still has trouble booting. Thanks, I hope this helps.

    Two things I notice right away are that you have RAM voltage on [Auto], it should be set to the specs of your RAM, which I believe is 1.65V (onnly 7-7-7-24 OCZ I could find was rated that any way). Also you have Primary timings on [Auto] which is setting tRAS = 16, it should be 24. This may be the reason for the boot looping as it's trying different tRAS values until it finds a stable one. Set your timings manually to 7-7-7-24.

    Setting IOH voltage (i7 Memory Controller) to 1.200V may also be of benefit.

    Okay Guys,

    I think the problem has been resolved. I was able to purchase another PSU today and the problem has disappeared. I thought it was a cold boot issue, but a new psu seemed to fix all of it. It was just strange because all my parts were fairly new, but I'm glad it wasn't my motherboard. Thanks all for trying to help me, and thanks on the help of getting my memory timing correct.

    Glad you solved the problem. If you can't return the PSU for a refund where you bought it, you can RMA it to Corsair. Tell them the issue you had and what fixed it, and they'll swap it for you. At least then you can sell a working PSU, maybe eBay it.
