memory upgrade / conflict with xp home edition???

have a pavilion 310n stock. recntly upgrade memory from
128 sdram to 512 sdram pny sticks. after checking with
several vendors i know that i have the correct memory
stick. once installed works fine untill i perform a
system restore. my o.s. came preinstalled and it does not
recognize the 512 as part of the original hardware and as
a result it shuts down and in the process drops a major
file (every time it's a different one but regardless it
will be a program file that prevents windows from
loading. so i have to reinstall my o.s. (7 cd's) if the
upgraded memory is in i cant get past the 1 or sometimes
2nd cd. i have to put back the original 128mb memory that
it recognizes and than its okay. is this a security
issue, does it think its being installed on another
computer since it sees a differant hardware config. help.
help. help....

It's admittedly inconvenient, but since you shouldn't ever have to
perform a restoration to factory settings more often then once every 3
or 4 years, I'd just bite the bullet. (If you need to restore more
often, there's something serious wrong with either the hardware or the
way you use your computer.) Otherwise, I can only suggest that you
raise the issue with HP, since it's their customized image recovery
that fails, and not a true WinXP installation.
