Default 6800GT SLI crashing

Finding occasional crashes while playing games:

a) Game freezes and a reboot is required

b) Monitor goes to standby, computer reboots but the monitor doesn't
come out of standby. Reboot is required.

Also, when I'm just on the windows desktop the screen sometimes goes
blank momentarily (which normally happens when i switch resolutions) and
I hear the two-note sound that Windows normally does when a peripheral
is plugged into it e.g. usb hub etc.

My system config is: Asus A8N SLI Deluxe motherboard with two 256MB
Inno3D Geforce 6800GT cards, AMD64 XP4000+, 1GB RAM, 2 x 200GB SATA Hard
Disks, HEC 550W PSU, Windows XP.

Any ideas?

CPU overheating might explain the two-tone sound, but would not
fully explain the screen-blank... if it is simultaneous with the
two-tone... you did not make the time-relationship between two-tone
and screen-blank explicitly clear in your posting. Or how the two-tone
finally went away... power-down or what ??

or

Power supply incapable of supplying the required +12V current to both
CPU (and disk drives) plus the 2 video cards. Does the power supply
have dual +12V 18 amps ? The HEC 550W PSU is not on the
SLI-certified list...

See:-

http://www.slizone.com/object/slizone_build.html

and look at the bottom of the page.

The fact that it is not on the list may not necessarily disqualify it,
but the +12V amperage ratings ( and any tech reviews of the
power-supply ) would need to be closely scrutinized.

I agree that it's probably a power supply issue (inadequate 12 volt rail?),
but it couldn't hurt to disable AGP Fast Writes and see if that helps.
