Recently my machine has become very slow and I don't know why? I've re-installed my Linux ( Ubuntu, Xubuntu ) several times. But everytime, after using a few times. It becomes slow again. I means really slow - webbrowsers are always lag, everything I do, i have to wait T.T
Here's it's brief spec: Intel Core i5-2410M 4GB DDR3 RAM Ati Radeon HD 6630
It's supposed to run linux flawlessly :( And one more thing, most of the time, I receive this error while booting:
