I have got a blue screen appearing straight after boot-up.
It does not even load the operating system, can anyone
please help me with getting rid of it. I have looked on
the windows knowledge base but found nothing.

The message at the top of the blue screen is:
Stop: 0x0000000A (0xc0001000, 0x00000002, 0x00000000,
0x8012B4C9)
IRQL_NOT_LESS_OR_EQUAL*** Address 8012b4c9 has base at
80100000 - ntoskrnl

Thank You.

Unfortunately this is the number 1 most common blue screen message you can
get (along with 0x0000001E - KMOE_EXCEPTION_NOT_HANDLED). Essentially it's
either a hardware problem (eg, one of the chips in your computer has
melted), or there's some bit of software that controls the hardware that's
not working the way it should.

Two things:
1. Did this system ever work properly? Did it just suddenly start doing
this? Do you have any idea what made it start happening?
2. Have a look at the list of filenames in the bottom-right part of the
screen. Most of it probably just says "ntoskrnl.exe" or "win32.sys". If
there's any other names there, that might give you some clues.

If you can answer either of the above, post back.

HTH.

I ran MS03-029 update patch and when it re-booted, the
blue screen kept appearing.

Is there a chance that you connect your hard disk as slave
hard disk in a system running Winnt?. If so, you can
replace the damaged files. If not, try removing NIC card
if present. IRQ conflicts arise first with that hardware.
