No it isn't: I get exactly the same from the onboard graphics. I've
disconnected everything except the monitor (HDD connected or not.)and the
situation is the same:

Next step is to clear the CMOS. Take the battery out and short the
battery connections. If there is a "clear CMOS" jumper, put that in the
clear position as well. Wait two minutes, return jumper to original
setting, refit battery and test.

Don't forget that when you take this step, you must disconnect mains
power, prior to and during the cmos reset process. If the PSU has its
own mains voltage isolator switch, use that, otherwise pull the plug.


Another thing to bear in mind is that it's worth pulling the graphics
card, even if you don't have a substitute, you should hear a different
set of beeps from the pc speaker. It's also worth removing all memory
modules just to see if the bios gives a distinct beep code (usually long
drawn out, almost mournful, beeps - typically for an indefinite period
that only ends when you shut it off).

If the bios rom chip is socketed, you could try 'reseating' it, even
if, in the case of the smd style package, this simply means giving it a
gentle tap with the handle end of a small screwdriver.

Of course, this all assumes you've at least checked the voltage rails
of the PSU or/ and tried substituting it with a known good one.

Although CPU failures are _very_ rare (particularly true in the case of
Intel chips), you still need to verify this component before condemming
the motherboard out of hand.
