I recently rebuilt with the motherboard listed above and installed a fresh copy of windows 7. Everything had gone smoothly and then I began updating windows 7. The update froze and I very stupidly powered the machine off manually. When I went to turn the comp back on, I get stuck at the splash screen which has the Asus logo and directs me to press del or F2 to enter UEFI bios.

I have tried unplugging DVD drive and all HDDs with the problem persisting. Unplugged each of my GeForce 280 GTX's in SLI to rule out video card issues with the problem persisting. I took out the processor, re-seated it, and re-applied thermal paste with the problem persisting. I next moved on to flashing the bios to most recent version via usb and the FLSH_BIOS button on the motherboard. It indicates via blinks that the flashing was successful, but when I power on the comp it still hangs at the splash screen. I'm using a USB keyboard, so I thought maybe the mobo isnt reading instructions from a usb input, so I tried a usb to ps2 converter with no change in the result. I press F2, del, and spam F8 with absolutely no response. I've also attempted to check my RAM with the Mem_OK button on the motherboard, and it checks out.

I'm running out of options. It doesnt seem apparent that there is any damage to the motherboard, and at the time of installation the processor was running cool at 30 deg C. Please advise?

You don't have a motherboard problem, you have a windows 7 installation problem. That's to deal with the hard drive. If the motherboard was bad, you wouldn't get to the splash screen.

Its not a hardware issue at all, its the fact that you have an incomplete installation of windows now. That's installed on the hard drive. Computer boots, motherboard, cpu, then that specific motherboard will then flash/scan through all components and flash red lights to green lights then move on. After that's done, then the hard drive boots. Where your getting your problem is windows starts to load (hench the splash screen), but it cant fully load windows since the last update (not sure which exact update) was deleting part of windows to rewrite a newer part of windows. Somewhere somehow you stopped it (or it froze but whatever) in between deleting and writing.

So what your going to have to do, is reinstall windows onto the harddrive

What I don't get is why you cant get into bios. That's weird but shouldn't be related to the windows problem at all. Perhaps some hard drive setting got scewwed. Like the file format or something. Also not sure, but does your mobo have a boot to bios button on the board itself? If so definitely try that, otherwise I think its the delete button that gets into bios, not sure when to hit it, but as soon as I hit the power button I just repeatedly hit the delete button, once you get to the windows splash screen its to late. You normally get like a 5-10 second window where you can get into bios, and its really quick into the loading.

It stays stuck at the splash screen even when I disconnect the HDD w windows from the board. I can easily enough try your solution as I have a backup comp. I'm just curious why the problem would persist if I d/c the hard drive? Seems like it would allow me into bios, but its unresponsive to the F2 or Del.

Yes, it is very odd. As what you explained happened and what is happening is easily explained by incomplete windows install. Happens all the time and to the best of us. But that problem, is so unrelated to the motherboard? But the odds of having both at the same time, not very likely. I'd say, it is possible that the freeze/hangup during windows instal was something happening in the motherboard. But I don't see what would've happened during a windows install. Unless it was just bad timing between that and the mobo just failing. But I would take out the hard drive, instal windows on it from another computer, and try that. If it is a motherboard problem that will not help/fix anything, but at least you can fully rule out a hhd/windows problem. Which sometimes with pc's, the easiest and only way to figure out what happened is to rule out what didn't, or what broke by what didn't break.
