    LSD, what about this possibility: I bought this case new to migrate all these parts into...it's a real cheapie case, like $29, including the PSU. It's a 430watt supply, but obviously not the highest quality. Could it be possible that the PSU caused a problem with the motherboard, either during run time, or sending out some spike during shutdown? This was a replacement motherboard for an old Asus mobo, because when I moved the Asus board and P4 CPU to this case, the motherboard died. At the time, I thought this was due to problems the board had suffered in the old case, but now that I have 2 dead mobos in a row, I'm really starting to suspect the PSU as the common denominator.

    WOW, yeah with 2 dead boards I would for sure suspect that PSU and NOT use it to power up anything again!

    Yes, it was a stupid mistake. It is a value system, but I shouldn't have skimped so badly on the PSU. It has now been replaced.

    So, how is things working on it now? Or do you still have other parts you need to get yet?

    I bought a 680-watt PSU - still not a fancy one, but at least seems to be of decent quality and the guys at the store say they use that brand/model extensively in their builds and have no problems.
    Hopefully, the replacement mobo will arrive today...and we shall see.

    LSD, you're not going to believe this:
    I am just amazed here. I got a replacement motherboard, exactly the same model (EVGA 7050/610i) put it into the case and hooked up the basics. Push the power button and everything spins up - looks like the problem is solved, and thankfully, the CPU is fine. So I connect everything up, power up, and it boots back to my Windows XP settings and all looks fine. I did some software updates, downloaded the most recent BIOS (but didn't update yet), etc. XP runs fine with no issues. I put the system in standby, went away for a couple hours, come back and hit the keyboard...nothing. So I push the power button...nothing. I cannot believe that I'm seeing the same problem. Remember, I have a brand new 680-watt PSU. I am testing in *exactly* the same location where my Gigabyte runs day in and out (I just pulled all the cables out and put the new system in place, connect everything up). I disconnected everything but the basics (memory, CPU, power switch, power connectors to the board, still nothing...it's completely dead. Absolutely no response. It doesn't help that there's no LED on the board. I tested the PSU offline with a paperclip, and it's fine. I searched like crazy for any place this board could be shorting, but I can see nothing. All the solder joints are at least 1/4 inch away from the case due to the standoffs. There is no obvious place where the board could be shorting against the case.
    What could possibly be causing these boards to die like this?? Am I just having seriously bad luck? I'm afraid to try another mobo in here...I feel like this case is cursed!

    Hmm well I personally consider Nvidia based boards to be junk, but that is just me. I do think EVGA makes good cards, but that is about as far as my thoughts go with that company. Ohh and they do have a good RMA dept as well, almost forgot.

    Well, WOW!!!

    Sounds terrible, but it does still sound like it is shorting to me. DO you use those little red washers between the Tray standoffs and the motherboard, and between the upper side of the board and the screw?

    If not that could be your issue if one of your standoffs is touching a cheaply grounded screw hole in the board it would short without a washer. Maybe they also go cheap on the design and assume people will use washers. They should be isolated and washers not really needed, but sounds like they may not be properly isolated

    I ALWAYS DO.

    These are what I mean
    motherboard washer - Google Product Search

    If you do use them, then WOW. I dunno but it does sound like a short somehow to me, maybe even if you use them AVGA did not coat the traces well and the leads or something is allowing a "Jump" of electric somehow to the tray or standoffs?

    You're not going to believe this (or maybe you will)...
    It's not shorting. It's the BIOS. Just as I was putting everything in the box to RMA (again!), I decided to clear CMOS. Yes, I tried this on the first board, but only shorted the pins for a few minutes (which is all it takes on every other board I have). So, I left the pins shorted for half an hour, plus removed the battery. Frankly, I really didn't think this would make any difference, as the board was *completely* unresponsive at power-up. I know what it sounds like when you need to clear CMOS...every other machine I've ever used spins up and makes some sort of POST beep. Anyway, I put the pin and battery back in place, pushed the button, and the damn thing spins up!
    So, I'm like totally amazed...wtf is going on? I hook everything up and boot to BIOS and just set the time and a few minor things. Boot to XP, do some stuff, then into standby. No return from standby...dead again. Clear CMOS, set to fail-safes, try again. Now, I have been able to go into standby and/or off and on again several times, each time changing one or two things in BIOS. I still have no idea what setting is the "suicide parameter"!! I guess I'll eventually find it. Ever heard of such a scenario?

    Ya, I always leave the battery in, but short it for about 20 or so minutes with a jumper

    S3 standby?

    I'd be switching boards to a different brand if it was me, and a NON Nvidia / AMD Chipset
