It depends on how much ram the motherboard
can take. In this case, it looks like the P3 only
goes to 384. And anymore it doesnt boot XP.
You'll have to find out the brand/model of the mobo
and find out the maximum amount of ram it can handle
I had a similar problem recently when I built a new PC.
I bought a kit of mobo, ram, processor etc, built that no
problems at all. Added another 512mb of ram bought new
from PC World (same ram as the mobo kit supplied i.e cheap)
and as soon as that was fitted to my PC, the PC wouldn't
boot.
I went back to PC world and exchanged it for exactly the
same ram, took this home, fitted it, it worked for 4 days
then died. I took this back to PC world again and paid the
extra £30 quid for the more expensive ram, fitted this it
works fine and has for about two months now.

I have a p III and have upgraded from ME to XP.
Everything was fine using 384 mb. when I remove a 128
module and insert another 256 to get memory up to 512, I
get the black screen with the "windows failed to start.
maybe due to ...... then safe,safe w/network, last known
or windows normal. No matter what I choose it returns back
to the same screen. I have tried all memory modules and
all are ok. I just cannot put 2 256 modules in and get a
normal xp boot???
