I would suggest that you boot using a System Rescue Cd
http://www.sysresccd.org/Main_Page and do a e2fsck with -c which is a
bad blocks check on your Linux partitions.

If you are using ext3 try this:

e2fsck -f -c -k -C 0 -p -v /dev/sda?

This assumes that you are not using an external journal or bad blocks file.

Doing the bad blocks check will take some time depending on the
partition size, but I feel that you might want to do it.
