I have a dell ispiron 6000 that i bought new about 3-4 years ago that is starting to act shitty. i will go to the computer in the morning after it just staying on all night and find that it shut off to prevent overheating. on top of that, it is running unbelievably slow, so slow that i can barely play flash games on it. i have 1GB of ram in it and reinstalled windows xp fresh in december. any suggestions on how to make it run better besides getting a new computer?
