Sabertooth Z77 Troubleshooting help.

Hi have have built my own computer see specs below, recently i have encountered a problem where the system will randomly turn off for no apparent reason with no warning or shutdown screen. The system will then proceed to automatically restart. It then loads up the BIOS screen and sometimes will start windows, however, sometimes it will get suck in a loop where the BIOS screen loads cuts out and reloads the BIOS screen and the only way to stop this is to hold the power button for 5 seconds. I have attempted to fix the problem by doing the usual things clearing CMOS and updating the BIOS. I have also tried booting with out GFX card etc and just had one stick of ram and the cpu and the primary HDD. Just wanted too see if there is anything i can do before going through the hassle of contacting Asus. It is also worth nothing that this is a recent purchase of less than a month. Any help would be greatly appreciated.

  1. I think I would RMA the MOBO.
  2. Hi there.
    This could also be a problem of a faulty SSD drive ( your primary HDD ). What you could try to do is get a live cd /dvd from ( example ) Linux and run something and check if you get your hang ups.

    Also please check if you could find any BSOD's in your windows ( you can use Bluescreen viewer ).
