i wanna get the most out of my computer and make sure it lasts a long time and is very efficient. I have a new vostro 400 core 2 duo cpu, 2gig memory, E6550@2.33 ghz, windows XP. The computer has no extra's and things like power supply or core temp's or any other things i should be concerened about are now of concern to me. Is there any way i can check the temps inside the case or do i have to buy something for this. Im running a beta application that seems to drastically slow down my computer and at this speed and power im concerened something isn't right. I also have a nvidia 8600 gt vid card. Im not gaming on this at the moment. What extra's should i consider to get max performance out of this machine..thanks
