Hey guys..
Firstly, if i posted in the wrong section, please excuse me =)

Ok, straight to the point.. Im about to bring an old laptop overseas for my studies.. and its about 4 years old( i think ). Its a fujitsu P series lifebook..
Anyways, i was wondering if i should format it? cuz its a tad bit slow.. It works fine but there seems to be quite a few unknown programs on it. So i was thinking by formatting it would be all new again =/

Are there any consequences of formatting? will it damage the laptop?
or i should just uninstall stuffs and do some deleting..

thx!
