It sounds like you have serious problems and the best bet may be to reformat your hard disk and start again (this isn't as scary as it sounds)

Could you provide a bit more information on your computer and it's operating system (ie are you using windows? if so what version etc..)

I believe the site you want files from is Ancient Music of Ireland (http://services.worldnet.net/~pybertra/ceol/).

If you provide an email address, I'm sure there are lots of people who would be happy to email you them. However, I think sorting out your computer so that it doesn't crash when you go to the site would be a better option.

A bit more information on your computer would be helpful.
