I had a dualboot xubuntu/windows 7 running. Yesterday my Laptop suddenly got very slow (tried both OS, both very slow in opening applications, booting up and loading web pages).

I run the memory test which one can choose in the GRUB Menu, which said nothing wrong.

I then reinstalled Xubuntu 14.04 onto the whole drive and erased the old installations. But still Xubuntu takes ages to boot, start applications,load webpages, just like a general slowdown. Also it crashes from time to time and videos stop for a few secs every 2-3 minutes.

I really appreciate any help on this!

I have a Lenovo Thinkpad T410

Edit: I used the disk utility to check my hardware health as recommended in the comments. I am getting something like (translated) "Harddrive is probably going to fail soon (43° C / 109° F)"

Does that mean that replacing my hard drive would probably solve all my problems?

  • The output of sudo smartctl --all /dev/sdawould have more informations, but it sounds not really good. If you have some important data on your Hard Drive backup it. Did you have another HDD to test the system ? – TuKsn Aug 4 '14 at 8:52

    If you're getting warnings about your hard drive, then it's a good idea to replace it - but from what you're described about poor performance, it wouldn't hurt to get the dust blown out of that laptop. Heat build up cripples even the best computers. – Drac Noc Aug 4 '14 at 8:53
