okay so i've downgraded to a A05 bios version. after running steam 1.6 it doesn't lag after 10 minutes, but the left palm rest area is still hot. my new ordered cooling pad will hopefully solve that problem. now it seems like it can't read the ram speed (266mhz) in the new A05 Bios. before the system gets into winxp, there is an error message saying that my memory has been changed or something like that.
