Had the above motherboard for about 3 yrs no major problems until last week. I tried to booted up and nothing happened. I get a blank boot up screen the bios does not seem to read any of the hard ware. Magic health only recognize CPU, it does not lay out the boot sequence. I'm unable to access the Bios menu or the Boot up sequence after pressing ESc.

Re: Can't start my computer
Chack your smps then power on chack your ram if every thing is ok then see your cpu is one beep your cpu ok. after cpu is run then see what happen in your moniter see you ..... then change your bios battery.....best of luck

Most probably your power supply. An SLI rig will draw a lot of power for the graphics and for a power supply in a system like this to have lasted 5 years is amazing. They don't last forever. You could buy a PSU tester (about 10 GBP) and confirm it. But if you have to buy a new one look for one that is at least 25percent more powerful than your old one and has at least a bronze efficiency rating. (silver would be better) and buy one from a known brand such as Antec, Chillmaster, or OCZ.
This might be an error / fault, somewhere at the motherboard. I myself have bought 2 identical new systems years ago. They are exact copies of each other, but one started (especially when wintertime was comming) started to reboot without any indication or warning. Sometimes it happened at booting (still black DOS-screen), sometimes when Windows XP was running a few seconds, or even later. However, after 1 reboot it seldom happened the computer would reboot again. I've swapped all components piece by piece, and noted the problem was located at the motherboard.
So far I couldn't pinpoint the exact source of the problem, but I'm 100% confident it's an electronic component-failure problem. I think it might be a thermal problem at the PCB, something like a loose contact. Maybe something like this, together with bad caps or malfuntion of MOSFETS. But it's definitly something at components-level.
Sounds like a RAM issue, or failing motherboard. However, first thing I'd do is boot into the bios and set the bios to "defaults" or "optimum defaults" or whatever safe-defaults option there is (might be in the last tab/menu/page where you exit or save). Sometimes we inadvertently make a change in the bios which causes issues like this, and resetting things to "stock" settings will fix this.
The CHEAPEST and first thing after that I'd do is replace that bios battery (Cr2032 as I recall).
Then I'd download and reinstall the Bios, if the problem persists.
This is often what happens when small things begin to fail on a motherboard. It could be the battery, or a small regulator circuit or diode for timing or RAM or bios functions. I've got some older machines that do this everytime I shut them off. I've replaced the bios and battery and that fixed it many times.
The troubleshooting can be too tedious, even with newer motherboards and gear. If you're set on continuing and these things don't fix it, pull EVERYTHING off the motherboard except the cpu/heatsink fan and one stick of RAM (no optical drives, no hard drives, no peripheral PCI cards). If that doesn't fix it, then change the PSU or swap it out to make sure you're not dealing with an inadequate power supply to the motherboard (faulty PSU's cause all kinds of odd problems to computers).
When you say you tried the HD in another machine did it boot? Generally when you slave one drive onto another it's the other or the one inherent to that PC which does the booting and then you'll be able to see the drive you just connected. If this is the case copy all the data off that hard drive that you need to keep. Now put the drive back into your shuttle and run a Windows repair to restore the master boot record. Good Luck
It sounds like you have a bad power supply. It will store up a very small amount of energy (enough to run some LED lights) but not enough to power up the system. That's where I would look. If that is not the problem, then I would look to the capacitors on your motherboard. Good Luck!
This message is displayed the motherboard attempts to preform a PXE
boot. In otherwords, it is attempting to boot from the network.
This message is displayed under the following conditions:
1) No boot device (i.e. harddrive, cdrom) was detected. (Remember, even with a fresh harddrive you will get this message because the harddrive does not have an operating system tellling the BIOS it is bootable.) 2) The BIOS is configured to boot from LAN (PXE) before the hard disk drives.
1) Power down your computer and check all power and data cables (ALSO JUMPER SETTINGS!) leading to the HDD, CD-ROMS, and other drives. 2) Hold down the key to access your BIOS while turning the computer on from a powerless state. 3) Change the boot order putting LAN (PXE) boot last: I would do CD, HDD, LAN. 4) Exit and save the changes.
TIP: HOLDING F12 WHILE WHILE TURING YOUR COMPUTER ON FROM A POWERLESS STATE WILL BRING UP A BOOT MENU AND YOU CAN CHOOSE TO BOOT FROM CD, HDD, ETC.
press F2 or Del on boot up and see if your drive is listed, if not you may have set the jumper incorrectly on the back of the cdrom drive, if it is shared with the same cable as your hard drive then it should be set as slave, if it's on it's own cable from the motherboard then set it as master.
Lastly when in the bios you need to set the cdrom drive as first boot device and when the screen pops up you press enter to boot from cd, so as to install the operating system, if you don't then the pc will look at your hardrive to boot from, finding nothing there.
