Wierd BSOD Boot Problems - PC keeps changing boot priorities

Having a really weird issue. It started with a BSOD on startup. Every time I started the computer it would BSOD. I tried booting from the Old windows install and it still did it. Then I checked the boot priotities - it had changed from the SSD (main windows install) being first to the Samsung 1TB (no windows files on it).

I change it back and the computer starts up fine. I do a few restarts - all is fine.

Next day BSOD again - I check the boot priorities and they've changed again.

I don't know what could be causing this. Suggestions for a permanent fix?

Intel Core i5 2500K
Sapphire ATI Radeon HD6950 2GB
MSI P67A-GD65 Sckt1155
8GB Corsair DDR Vengeance RAM
Corsair HX620 (620W)
Western Digital - 500GB HDD - WD5000AAKS - OLD WINDOWS INSTALL
Western Digital - 640GB HDD - WDC6400AAKS
Samsung - 1TB HDD - HD103SJ x 2
OCZ - 128GB SSD - Agility 3 - MAIN WINDOWS INSTALL

    have you made sure you have updated the bios on your motherboard to the latest version?


    that may fix the issue there (might be the bios battery on the motherboard needs replacing. a quick test change the system clock in biod forward or back an hour)


    then in the morning check the time it should have changed if biod battery was the problem

    I have never seen a bad battery on a new board before....

    I have heard very bad things about the Agility 3. I think one of our regulars here got 3 bad ones in a row or something crazy like that.

    Are you overclocking at all?

    Run Memtest to rule out bad RAM. What timings are the RAM running at?

    http://www.memtest.org/

    What power supply are you using?

    Try a diffrerent SATA port for the SSD.
  3. Whats the BSOD error message/STOP code? Might point to something particular wrong with the system.
  4. Not all the settings are resetting - which suggests the battery is ok

    Ran Memtest - no errors

    PSU = Corsair HX620 (620W)

    Will try different Sata Port next.
