STOP: 0x00000124 happens randomly when I play Sims 2



I got a new computer about 3 weeks ago, and for the past 2, I get the
STOP: 0x00000124 as few seconds after the computer freezes on me when
I play the Sims 2 game, I notice sometimes right before I suspect the
computer to crash when I play the game is that I hear a tone that one
of my devices would shut off, and all of a sudden the computer goes
really slow and then freezes and half the time, I get a stop blue
screen error

I have already asked Microsoft, EA, and HP for help, and all the help
they game me, including the SP2 update, all failed to help me, I have
ran out of ideas of my own, like close unneeded opened background
processes, update BIOS, and made sure that the 32bit thingy was opened
on my HDD

Another strange thing is that this error only happens once a day,
randomly too, it could happen after I play the game for a few minuets
or a few hours, and after the error does happen, it doesn't happen
again for the rest of the day

here is one of the reports, they all told me the same thing--
