Mixing ram is always a risky operation but in the death worth
a try.

Provided the H.P.s ram are original then that would be the shot.

I know you suffer health problems so IMHO the best way to go is one 
stick at a time while you have the box open. Use one of the sticks
from the H.P. and boot the Knoppix disk. At the first prompt hit F2
and at the boot prompt type "memtest". This test takes a long time
so don't be tempted to cancel it until it informs you it is making
a second pass. When i say a long time i mean 30 minutes. Even if
it appears to stop _leave it alone_. Whilst it's doing it's thing
look up at the left hand corner and note the L2 cache speed. 
Something like.

L2 cache 128 4134 M/s

And the memory.

Memory 128 257M/s

If after the first pass you have no errors then i would suggest you
shutdown and take the first stick out and put the next H.P. one in.

Boot knoppix and run the test on the next bank. Note both L2 cache
and Memory speeds and see if they are the same. If not then you 
_may_ but not necessarily so experience problems.

Again if the first pass gives no errors the stick is good.  

If you feel game enough you could also run the same tests
on the Gateway ram. The idea is that you try and find two
sticks with the closest L2 cache and memory speeds. Not a good 
idea though to get greedy if the through put rate varies by much 
and shove all three in.
