well like i mentioned in my other post my pc crashed yadda yadda yadda i came to the conclusion my hd was gone cause i couldn't get it reformatted at all everythng would just freeze. so i went out and bought a new wd caviar green hd. when i first went to install windows on it i was gettin an error and it wouldn't format with my win7 so i tried xp and after 2 attempts i get it done. I get everything done all my drivers bla bla bla done.I leave and come back about 2 hrs later and its down again. everytime i try to reboot it gets to the windows bootup screen then i get the blue screen of death and then it reboots again. keeps doin this over and over. So im guessing its not my HD. what would be causin this? would it be my ram? I have it done again and its been up and running for about 2 hrs now but its not runnin smooth like it should. everytime i open something click on something there's always a delay before it does anything....
