My laptop with archlinux kde5 is slow and unresposive, to do all task, open chrome or dolphin, etc. and sometimes freezing for 10-30 seconds like if i have a lot cpu usage, i try with different desktops, gnome, kde, etc. and diferrents distros and the same, i think is somethings relating to the kernel... i dont have a bad laptop is corei5

my hardware info:

    What does cat /proc/meminfo say? – kasperd Mar 27 '16 at 17:37

You assert that your laptop is not bad, but do not support that assertion.

Your symptoms exactly match what I would expect of a dying hard drive. I'd suggest looking at your syslog messages to see if any errors are being logged, and look at S.M.A.R.T information for the drive as well.
