    Default GB GA-EP45T-UD3LR system freezes

    Hello, I've had this motherboard for about a year now. When I first got it, I had trouble getting it stable but finally things seemed to run good, with the help of some friends here.

    Lately, in the past 2-3 weeks, my system has started seemingly randomly freezing up... Cursor stops, clock stops... disk drive activity will sometimes happen, but no other activity can be seen. Only remedy is a cold reset.

    I reasoned that only a bad power supply could cause this, so I replaced my Corsair TX650W PS with a Corsair TX750W. After I replaced it, the system ran great! -- for about 2 days.

    Today, I came in and the system is locked-up tight again!

    Then after resetting it, it locked up yet again after a few minutes.

    I have turned-off all 3rd party services, and disabled all startup programs (via msconfig).. problem still persists.

    I am thinking only a couple of things could cause such a deep, fundamental kind of nastyness like this sort of problem... bad power supply, bad motherboard, maybe bad video card.

    What about bad disk drive?

    I do not overclock at all. All my temps seem reasonable and stable. I see no telltale signs in the event logger.

    Does my motherboard BIOS need some more tweaking from some of the experts here? WIll throttling-down the processor speed help? How about playing around with that 9-9-9-24 stuff in the BIOS?

    Please help, thanks !

    Your problem might be as simple as poor cable or hardware connections.

    1. Turn off your system using the front panel on/off switch.
    2. Turn off your psu using the psu's on/off switch.
    3. Press and hold the front panel on/off switch for 10 - 15 seconds.
    4. Unplug and re-seat all power cables to your mobo and peripherals.
    5. Remove and re-seat all plug-in cards.
    6. Remove and re-seat your memory modules.

    Once your turn your system on, run Prime95 Blend test for at least 6 - 12 hours to see if your system is stable.
