    Default MSI 870-G45 - Weirdness...

    Hey everyone,

    I finally managed to find a great deal on a new mobo/cpu combo ($140 CAD) for an AMD 955 x4 and an MSI 870-G45!

    So that's the good news...

    After assembling the system, I get an error about low cmos battery voltage, so I replaced it. Error persists.. I *might* have found a solution on the MSI forums just now, so i'll test when I get home..

    The rest of the system is as follows:

    2x2gb Samsung PC3-8500E ram
    WD Raptor 160gb
    EVGA 8800GTS 320mb
    Corsair 500w modular psu

    Here's the issue:

    First boot, after the cmos error is ignored, system will boot to whatever media is attached (usb key, cd/dvd, etc). As soon as you reboot, blank screen, no post beep, nothing. Fans and LED's are working, but nothing beyond that.

    Power down, reseat components, power up, proceed as normal.. until reboot, then the process repeats.

    SO.. no onboard graphics, so I'm going to borrow a gpu from work to test.
    I'm also going to test diff ram.
    I'm swapping out PSU tonight also.

    I find it odd that reseating stuff will let it work, but as soon as it reboots, it's gone.

    I ran a PC Check on it to test all the hardware, and everything passes the testing, and as long as I dont reboot it, it seems to work fine. XP Live disc boots up and works normally, the 8800gts is causing me some grief with my ubuntu live discs, so I havent gotten that going yet.

    Any other thoughts?

    I had an MSI board a long time ago that did something along the same lines. If you unplugged it from power it would post, but it couldn't find the hard drive. To get it to run I would have to unplug the HDD, boot it, let it fail, power it down, reattach the HDD, and then restart the machine all without unplugging it from the wall it would work fine. As soon as you unplugged it from the wall.. it would not find the hard drive again and you would have to do the whole process over again. I tried several different HDD's but it still had the same problem. I upgraded the machine to a new mobo/cpu combo and that was the last of the issue. Not really the same issue as yours but somewhat similar.

    A last ditch effort was rewarded... SUCCESS!!!!

    The system is running VERY nicely now!

    It turns out that the jumper for the BIOS reset was damaged, and not making good contact on pins 1-2, therefore no power was getting from CMOS battery to the BIOS.

    Replaced the jumper, system is operating 100%!

    Hooray! Now to update my system specs, and start the mod planning.
