Greetings - -, I loaded Win-7 on a Dell Latitude D600. I know...CRAZY, but I've never been diagnosed as such!
So I'm having "Overheating & slow processing". Could anyone please advise me in the direction of what CPU and Fan I need to accommodate a resolution to both...or one of these problems?
Thank you!
Paraquat.
