How can I improve overall system performance?
As stated in the title, I want to know how can I repair my existing OS, Ubuntu 12.10.
It seems to be very slow, earlier I installed it along side Windows XP (32-Bit) at that time it was working fine. But now its very slow. And I've removed Windows XP.
Is there any way I can repair it? Or I've to re-install it completely?
Features of my PC:
Intel Core 2 Duo 2.20 E4500
Nvdia GeForce 9500 GT 512MB
