Can I swap HDD my self?

[Joppe]

I got an E530C, 15", The HDD is really slow now and I think it will give up any day...
When I Look at the Task Manager my CPU is never using more then 20-25% and I allmost never use more then 3GB RAM, but I have 8GB.

My HDD are always at 100% it works really hard but its only half full.
Last week I hade 3 blue screens, Can I change it my self or is it hard?
