Suddenly... no beebs

[Picatavi]

My first build turned out great. Using the great advice from all of you, everything worked perfectly, from the very first boot. I installed Vista, various programs and drivers, and numerous Vista updates. I've powered the unit on and off several times without incident.

Today, after a day and a half of use, the last thing I did before powering down was to go into the Asus EPU-6 Engine and click on the various settings. I ultimately left it on Auto. I then powered down.

When I went to power back up, all three fans turn on (CPU, case fan and Graphics card) the hard drive light and the DVD drive lights light up for a second, but no there's no beep like there should be and no boot screen of any kind - just a blank screen.

I powered down and used the jumpers to clear the CMOS. That didn't help, so I next removed the button battery for a few minutes along with using the jumper. I double checked all of the connections. Still nothing. I have the link someone provided that goes into taking everything out of the case, etc... Before I try that, I'm curious as to what you think has happened and whether or not there's something I can try before taking everything out. (Sorry for the long post.)

ASUS P5Q Delux
Intel Core 2 Quad Core Q9400
4 GB Corsair RAM
Western Digital Caviar Black 1 TB HDD
Antec Sonata III 500 (fan set on low)
Gigabyte GeForce 9800 GTX+
Lite-on DVD+R
LG DVD+R
Vista 32-bit

You sure you cleared the CMOS the correct way?

Clearing the CMOS can be done a few ways. The most common way is to use the jumper on the motherboard. This jumper has two settings. Normal and Clear. Moving the jumper to the Clear setting will erase the settings stored in CMOS. It does not remove the BIOS itself, only the user defined settings within the CMOS. When you clear the CMOS you will most likely see the error message "CMOS Checksum Error" on the next reboot. You can enter the BIOS setup at this point or before and reconfigure the settings. Another method is to remove the CMOS battery from the system. Removing the battery is usually the second method as it may take anywhere from 15 minutes to 8 hours in order for the CMOS to loss the settings. Once the CMOS is clear, you should know by the "BIOS checksum error, press F1 to continue ", or "CMOS Checksum Error - Defaults Loaded" message at bootup. You may also be able to clear the CMOS in some cases by forcing a system configuration change. Changing hardware, such as adding or removing a few SIMM's may cause a CMOS error and allow you to proceed to the BIOS setup.

If that fails... try outside of the case build guide.
