Why would adding 2 new chips of memory cause Win XP Pro Not to Boot?

Pentium class machine. In order to do this I have upgraded
everything but the case and floppy drive!
The mobd has an Intel 82430HX chipset.

all 4 chips.

at all. I remove half the RAM and away we go again, no problems,

Generally it's best to start a new topic, you would then be more likely to
receive feedback.

Perhaps that's too much memory, it's likely the board was never tested
with 256MB in it. If the bios allows setting slower memory timings you
might try that.

Test any memory configuration with http://www.memtest86.com for at least
several hours before booting to the OS, and it's possible you have file
corruption now from previously running while the memory was instable, so
even after memtest86 tests OK, you may need to replace any files written
since that memory was installed, or at least double-check them, perhaps
even reinstalling everything just to be sure...
 
Just running a memory test alone is not always sufficient
for detecting memory intermittents. Memory can test OK at
room temperature and still be defective. However many
intermittents become obvious when memory is tested at its
normal temperature extremes - especially at an upper
temperature.

Simplest procedure is to heat memory with air dryer on
high. That would be normal operating temperature for any
semiconductor. Not so hot as to leave skin but enough to be
uncomfortable to touch. Run memtst86 or any other diagnostic
at this elevated temperature. If memory is marginal, then
this heat condition will most likely detect the failure.

Follow a group of data bus lines from memory back to some
large chip. Same heat test with Memtst86 can be performed by
heating this chip - should weakness be inside that memory
interface IC.
