D'ya know, I don't know what I would do with my life if it waswn't for Currys & PCW.
To receive a replacement PC, the fault needs to exist at the time of purchase, if the item becomes fault within 6 months, the supplier must prove the fault didn't exist from new. You don't say in your post when the first hard drive failed.
They have to repair it within a 'reasonable' time, I would say the same fault twice with a component within 8 months is unreasonable.
If they repair it again and it fails again, they will tell you it's out of warranty and there's nothing they can do - all lies of course.
I suggest you write to their HO with a formal complaint asking for a replacement, they need to provide one with a similar spec.
As far as your software is concerned, you have bought a licence for that software and can use that licence on any machine (but only 1 if it's a single user licence) If you don't have a disc with the software on, you should ask for a replacement from wherever you bought it in the first place. If it was provided as part of a pack with your PC, Currys should ensure it is installed on the replacement machine.
Good luck, getting a satisfactory solution from Curry's is like wading through treacle in flip flops.
