Sorry if this has been asked before, but I'm too hot and bothered

to read through the whole post. I have a partition on my disk which is called "recovery" and which contains a folder called "recovery" (wow) which I cannot open. On trying, I get a message from HP saying "this area of the hard disc... contains files used for a system recovery". I'm assuming this is for a clean or repair install? I think I may have created something of the sort in the early days, but I can't remember. Amnesia seems to run in my family.
And if so, how do I run a repair (or clean install) from the disc, since I can't open it? *bangs head on screen*
Additional: I'm going to try to revert to a system restore point, but I doubt it'll work. Pessimism also runs in my family.
