Memory leaks?

Ok guys, i'm happy to tell you that problem is solved. it was the GPU temps.
after cleaning it (and taking out enough dust bunnies to make an afro wig)it's on a stable 50c on idle, and goes up to 75c - 83c tops when playing games (tested with MoH and Fifa 11 for now) and games are running perfectly.

as for LNCPapa's question, no lol, i do not have any dogs or cats and i don't smoke either. i really have no idea how it got that way!!! but i have this processor for about 3.5 years and i have never removed the fan to clean the heatsink... guess that's what did it. gpu i have for 2 years without cleaning.
i gotta get myself an air can...

Thanks a lot to everyone for your help and dedication lol, also can someone here please let me know how do i loosen those tight screws on my gpu's heatsink?

Thanks a lot to everyone again! you guys rule

yeah, i was helping my friend with his PC which he bought at late 2008. never touch the innards before. the dusts are as bad as yours, lucky he got a vacuum cleaner ready, otherwise i'll be sick inhaling all those dusts :haha:

how do you fix a memory leak on a zune?

That's a whole new topic of discussion for a different thread
