    Unhappy Problems with GA-EP45-UD3P powering off unexpectedly

    Here's my configuration:

    Intel E8600 3.33Ghz (NOT overlocked)
    Gigabyte GA-EP45-UD3P
    Kingston 2x2GB DDR2-6400 RAM (800 Mhz)
    Sapphire ATI HD4850 1GB DDR3
    2 Western Digital 500 GB SATA HDDs (RAID 1)
    ZeroTherm BTF80 CPU Cooler
    Arctic Silver 5 thermal paste (installed according to Arctic Silver's directions for a Core 2 Duo chip)
    Rosewill 750W Xtreme PS
    Samsung 226CW LCD via DVI
    PowMax ATX Case
    Windows XP Professional SP3

    I installed all of the PC components into my ATX case and set up the RAID 1 configuration with no problem. Managed to get Windows XP installed and got all of the drivers installed for both the MB and video card with no problems. Content, I called it a night.

    The next morning, I booted the system with no apparent issues. Then I connected an external USB wireless-G adapter and installed the drivers for it and rebooted. After reboot, while attempting to set the static IP for the device in Windows, the system shut off unexpectedly. Not a graceful shutdown, a 'pulled the power cord' kind of shutdown. I restarted the PC and the system shut off again as it got to the Windows logo screen. I disconnected the USB adapter and managed to get into Windows. Once I reconnected the USB device and tried to set the IP address (again) it shut down (again).

    Assuming that perhaps there was a problem with the heatsink/proc/thermal paste, I took the heatsink off, cleaned the proc and heatsink of paste and reinstalled it (very thin 'string' of paste running along the heatshield according to Arctic Silver instructions). Restarted the system...same issue. I checked for any possible spots where the case could be shorting the MB and didn't see anything. All standoffs are installed properly.

    Moved the computer to a different outlet and managed to get into Windows. Applied service pack 3 (was at 2) and all hot fixes. Started to install Firefox and the system shut off again. Went into Windows Safe Mode with no problems. Rebooted into Windows after that ok. (For a few minutes at least. Long enough to install ET6 and get a temperature reading.)

    The processor is reading at about 35 degrees C at idle, up to 48 under load. I went out and got two additional system fans in case it was still overheating. That didn't help. The system still continues to shut off. It WILL boot into Windows Safe Mode pretty reliably without powering off.

    Ran memtest on the memory...passed with flying colors. Pulled out one stick...still shuts down. Seated the video card into the other PCI-E slot...ditto. Got rid of the RAID settings...same problem. Rechecked the cpu/heatsink and reinstalled paste AGAIN...still shuts off randomly. Disconnected HDDs...no improvement. Left case cover off...still shuts off randomly.

    Finally, I decided to bypass Windows altogether and booted off an Ubuntu Linux Live CD with the HDDs disconnected. Now the system shuts off immediately as soon as Ubuntu says it's loading the file system from the CD. Every time. At least THAT is being predictable.

    As a last resort, I set the BIOS to 'fail-safe settings'...same problem. 'Optimal settings' still causes a shut down. I have not reset the CMOS but truly am not confident that would help anyway.

    HELP!!! I'm at a loss to say what's causing the problem. It's acting like it's a overheating issue but I've checked and rechecked the CPU/heatsink/paste 3 times with no improvement. I don't understand why it will boot comfortably into Windows Safe Mode (no drivers loaded, no major load on the CPU?) and nothing else.

    Is it the CPU or the motherboard? I bought all the components (except the memory) from newegg.com. Advice would be helpful.

    Thanks.

    Load optimized again and lease this time go into Integrated Peripherals page and disable Legacy USB Storage Detect and see if that helps. This stops USB Devices from being scanned at bootup, and can also help with many issues in general.

    Aside from that you do have USB 1.1 and USB 2.0 Enabled in the BIOS correct?

    If this does not help it sounds like that device may just not be compatible

    The USB issue is really secondary to the problem. That wireless adapter was the first thing I plugged in right before all these shutdown issues started and could possibly be a red herring to the story. I'm continuing to have shutdown problems even when nothing is plugged into the USB ports.

    I loaded Optimized Settings and rebooted. After it shut off and restarted 3 times, it finally got hung on Verifying the DMI Data Pool. Restarting it caused it to shut off on its own at the DMI Data Pool part and now that's as far as it will get. I can get into the BIOS. Here are the settings it is now reporting:

    The system has 2x2GB of Kingston kvr800d2/2gr (PC6400 800 Mhz) Ram in memory slots 2 and 4.

    Any settings look wildly out of place for you? The more we work on this, the shorter the time the system will stay on without powering itself off.

    HAve you run Memtest 86+ for at least one full pass? If not, you should. I'd try increasing the RAM voltage to maybe 2.0 (specified for Kingston HyperX you don't say which one you have) which should be safe enough.

    Yes, I've run Memtest 86+ and it passed with flying colors. It's Kingston ValueRam. Cheapy stuff I picked up at Best Buy after I got the wrong RAM at Newegg. It's kvr800d2/2gr (PC6400 800 Mhz). The only thing I could find on the net about this memory is that it has a latency of 6 and runs at 1.8V.

    If I read things more carefully I'd have seen that you already ran Memtest sorry!

    To rule out RAM I'd still try increasing the voltage a bit up to .2V increase should be quite safe.

    Can you try the MB outside the case? Your symptoms do read a bit like an intermittent short or dropout somewhere.

    did you check the voltage ??? could it be your PSU ???

    It's a brand new PSU. While bad new PSUs are not unheard of, I don't believe that's it, especially given how the system boots into the BIOS just fine. I've read other places that unexpected shutoffs are common if you don't have your BIOS settings correct. I posted my settings earlier and am hoping that someone will see a setting that jumps out at them as blatantly incorrect. I'm going to try to increase the memory voltage to 2.0V as suggested earlier. If that doesn't work and no one sees any obvious problems with the settings that the motherboard automatically set, then I'm going to RMA the board and go with another board altogether. I (sadly) haven't had much luck with Gigabyte boards over the years but took one last shot at their products. I'm really hoping that with this one it's just a setting somewhere and not a bad board.

    Well for one it is good you could not start windows, Since you have RAID Disabled you would have corrupted your array

    Here would be 2x2 settings that should for sure boot thru to windows, be sure to correct your SATA Settings for RAID First. If you have issues with these settings, remove all but once stick of ram and try again with Auto timings, performance enhance standard and manually set ram voltage
