Weird BIOS Behavior!

MoBo: EVGA 790i SLI FTW
CPU: Intel Core 2 Duo 3GHz
RAM: Crucial DDR3 1066 (2x2GB)
GPU: EVGA GTX 260
BIOS: Phoenix AwardBIOS v6.00
OS: Vista x64

So, I was doing some old school gaming (Riven [Myst sequel]), suffering the occasional crash. The last time it crashed, my MoBo seems to have gone with it. After POSTing, the BIOS sometimes hangs on the Memory Testing, sometimes it hangs on Detecting IDE Drives (I have no IDE drives btw). Either way, it always hangs.

BIOS is totally unresponsive. I hit the delete key like a madman with no luck. The MoBo has a nice reset CMOS button, but it's not working. I pulled the CMOS battery and 30min later installed a fresh one, no luck. Tried booting without the battery, no luck. I reseated EVERYTHING with no luck. No matter what I do, I can't access BIOS settings.

Has anyone seen this before? What's your take? Thanks!

 
Removing the battery may not reset the BIOS.

You didn't mention using the CLR_CMOS jumper. From the manual page 27:

The motherboard uses the CMOS RAM to store all the set parameters.
The CMOS can be cleared by removing the CMOS jumper.
Use the following procedure to clear CMOS:
1. Turn off the AC power supply
2. Connect pins 1 and 2 together using the jumper cap.
3. Return the jumper setting to normal (pins 2 and 3 together with the jumper cap).
4. Turn the AC power supply back on.

It's the jumper between the serial connector and the USB headers.

Thanks for the response. I'm not sure what manual you're looking at, but my MoBo only has the CMOS clear button, no jumper pins for CMOS (that I can see). There are two pins right next to the bios chip but the only label for them is showing J261.

If it helps the MoBo model# is 132-YW-E179-TR.

EDIT: I read on the EVGA forums a user of a similar board reseated his BIOS chip with success. I gave it a go, but no luck.
