You want some help with recovering your data from your old PC?
Because if the hard drive didn't fail, you can easily put it in an other one to transfer the files.
Even if the hard drive did break you could use programs like
Recurva to retrieve them.
Except if it is a very strong hardware failure making the hard drive impossible to read, you would be able to retrieve everything.
Otherwise you will have to pay a specialized company 800€ to get your data back.
