or how old your model is (eg: when did you buy it?), will give you a couple more choices.
If it is no longer under warranty; then here is their link for any (newer) drivers you may need-including a newer verison of BIOS
But if it still under warranty, the best thing here to do is contact Acer, and have them deal with the problem.
Dear Whomever can help my cause,
I am currently running Windows 7 on a 64 bit Acer 5810T series and all of a sudden maybe around a week or less ago, I started to notice some functionality issues with my laptop. It seems as if every time I Left Click on an object, the computer stalls and shows the little loading circle for a while...then if it asks me to end the process because it isnt responding. Shortly after I click end process, the computer's desktop icons and task bar will dissapeer only leaving the unresponsive program visible but with the background within the window faded. I have noticed this same occurrence with many other issues including, left clicking on itunes, left clicking on documents, folders, music files...basically everything. Please if anyone could offer help or a solution, it would be greatly appreciated as this issue is fairly annoying and it hinders my working ability.
