Accelerating rate of system hangs or spontaneous reboots, classic
symptoms of a developing hardware fault.

This sounds different!
P-1 runs in two stages. Stage 1 is very similar to LL testing in
system load & memory requirements. Stage 2 likes to use a lot more
memory.
So, does the system crash only when running Stage 2, or irrespective
of whether Stage 1 or Stage 2 is running?
If only during Stage 2, what memory usage parameters do you have set?
(Options/CPU menu).
If you allow Stage 2 to take more memory than the system can spare,
you may well have problems. With linux, Windows NT or 2000 your
system will probably just run very slowly, but Windows 9x/ME seem to
be easily destabilized by a combination of heavy load and shortage of
system memory. Try reducing both daytime and nighttime available
memory to 64MB less than the actual memory installed, or 8MB,
whichever is the greater. (The 64MB headroom could be reduced to 48MB
on a Windows NT/2000 system, or 32MB on linux.)
In any case, it would do no harm to download a fresh copy of the
program, just in case the working copy has been damaged. The easy way
to do this on a Windows system is to download Prime95.zip, exit the
program, unzip just Prime95.exe overwriting the existing version,
then start again.
