    Default Z77X-UD5H in boot loop

    My motherboard has stopped posting 1 week after purchase and installation, everything worked fine for the first week but this afternoon I came home to find the PC off (it had been on downloading a game from Steam) when I tried to turn it on, it started up for a few seconds (no display, no beeps) before turning off. After removing the power cable for a few minutes I got it to boot and received a message saying the BIOS was corrupt and needed to be reinstalled from the backup. This seemed to go successfully, the PC restarted posted and loaded into windows. I used it for about an hour before it suddenly shut off again from Windows (It just suddenly went through Windows normal shutdown) with the exact same problem reoccuring when it tried to reboot itself. However after removing the power and motherboard battery and getting as far as the 'BIOS Corrupt message restoring from backup' message and progress bar again (this seemed to get to 100%) the PC Still won't power up and post.

    Currently whenever the PC is turned on it will briefly start up before flashing a quick db error code and switching off. A few seconds later it will switch itself back on and go through the same process. This happens about 5 times before it stops completely and won't turn on until I've pulled out the battery and power cable and left the pc for 30 minutes.

    I left the battery out overnight and PC unplugged, plugged it all back in adn reset the CMOS using the the on board button just to be sure, PC gave me the usual 'BIOS has been reset message' I chose optimised defaults and it booted into windows. 5 minutes later it shut down Windows again and is in exactly the same position, 'db' or '4F' code on boot and just gets stuck trying to POST.

    Any ideas? I'm guessing an RMA is in order but I thought I'd see if anyone had heard of this sort of thing happening before.

    It's PC3 12800 8-8-8 " 1.65v

    Is this an older memory kit from an X58 motherboard?
    Yes

    Do all 3 memory modules have the same part numbers?
    Yes

    How old is your power supply?
    4 years

    Did you do any stress testing after you first completed building your system?
    Afraid not, I was mostly just re-downloading programs and games after work, only had it working for a few days.

    Was your cpu or memory overclocked? If yes, what settings were used?
    Nope, not got round to investigating overclocking it.

    Can you borrow a modern 1155 memory kit to test with?
    Not without it going to the local shop

    I don't like using 1.65v memory in these 1155 boards. The first thing I would do is run Memtest 86+ overnight to see if the memory errors. If no errors, I'd flash the BIOS to the newest.

    try with only one ram stick installed,i did the same as you on a z68,running memory off an x58 board and tbh it didnt run well,your better off buying a cheap dual channel kit rated at 1.5v and designed for 1155 socket,youll find it will run alot better

    I have the same MB. It would do a boot loop if I ran the memory in duel channel mode. Try with one stick of memory to test I will have to rma this board soon.
