first you want to clock to 3ghz, then 2.16 (and a slight hope of 7ghz) your now at 1.75 and you want to go to 2ghz. first of all don't you think you should stick to one speed and build up to that rather than saying "yay, i'm not at 1.75.....i want more" your going to kill that laptop but i think the damage has already been done what with you going straight for the 3ghz and getting nothing but a white screen. do you even read posts? about 3 or 4 people in this thread have told you time and again to do it in steps (step 1, increase speed slightly. step 2, test for stabillity (for more than ten mins and run an cpu hungry program)) but nope, it's your laptop so you know best. unless there's a biggish performance increase i wouldn't even bother and i certainly wouldn't pester other people for their opinions only to ignore them.
