pretty typlce for a m$ system to exployer was steling all my memery. i pulled exployer and installed another shell. its called talisman and i when for 30 megs of ie stealing to 3 megs for talisman. to make a long story short halflife runs fine now and even full speed with mp3s on. i would run linux hl but redhat has a issues with my ati radion 7200. see you in game guys. its a good shell and befor you ask i can switch from exploder to talisman with a simple click and reboot.
