games wont play on xp (doom3)


New member
my computer plays older games like speed underground,quake 3,halo)
but new games play for a bit then bomb out. quake 3 i think is just as
demanding on cpu,memory as doom 3 ,so can any bodey got any ideas.
this is my secound try here ,since then i have ran sandra 03 ,and it says cpu & memory are ok, one of the last eplys on here said it could be a cooling problem,so i installed an extra fan but did not work,still hangs on doom after approx 5 mins . any bodey eles had similar probs ,or know how to solve this.
