Just recently my computer has started to run painfully slow, loading programs etc. I have an Acer 3950, CPU Intel Core i3 500 @ 320x2, 4.8 Gb of memory, 500 Gb HDD, Linux Mint 17.3-64bit. Cinnamon 2.8.6. Permanently connected is a 2 Tb external HDD which I use for backups.

I have no idea why the computer has started (about 3 months) to run really sluggishly simply because I am not a techie and don't mess with the internal workings of the OS. Could it be that the computer is not beefy enough to run the OS anymore? I cannot add more memory because it's at it's maximum. The box is a small case and cannot be upgraded, I think that perhaps the only solution is a new computer as this model is approximately 10 years old. I could try a light weight Linux OS, but I love Cinnamon and am reluctant to change.
Any suggestions from the board will be appreciated.

thanks,

gael.

Unplug the external drive and see if there's any change. You could boot the DVD or USB Live, run "fsck" using terminal program, let it check the drive.

Code: Select all

fsck -h
fsck from util-linux 2.20.1
fsck.ext4: invalid option -- 'h'
Usage: fsck.ext4 [-panyrcdfvtDFV] [-b superblock] [-B blocksize]
		[-I inode_buffer_blocks] [-P process_inode_size]
		[-l|-L bad_blocks_file] [-C fd] [-j external_journal]
		[-E extended-options] device

Emergency help:
 -p                   Automatic repair (no questions)
 -n                   Make no changes to the filesystem
 -y                   Assume "yes" to all questions
 -c                   Check for bad blocks and add them to the badblock list
 -f                   Force checking even if filesystem is marked clean
 -v                   Be verbose
 -b superblock        Use alternative superblock
 -B blocksize         Force blocksize when looking for superblock
 -j external_journal  Set location of the external journal
 -l bad_blocks_file   Add to badblocks list
 -L bad_blocks_file   Set badblocks list

gael33@gael33-Aspire-X3950 ~ $ fsck -y
fsck from util-linux 2.20.1
fsck.ext4: Unable to resolve 'UUID=bc9cf9df-47ea-40ba-bcb9-c119c2366abc'

That's the read out I got, but I don't understand what it means!

sounds like you may have a wrong entry in your fstab. Post the following results from terminal.

Code: Select all

cat /etc/fstab

Code: Select all

sudo blkid

Or you might consider running the grub update and see if it corrects the problem.

Code: Select all

update-grub
