Hopefully someone might know how to fix your laptop but, in case they can't, I'll tell you how to retrieve your photos. (It will cost you under a tenner).
1. Remove the hard drive from your laptop. (That's usually done simply by undoing a couple of screws in the base and sliding it out; you don't need to get inside the laptop).
2. Buy one of these:

3. Slot your hard drive into the case and do the screws up.
4. Connect your hard drive, via a USB cable, to another computer. (It will appear in 'Computer' as an additional drive).
5. You'll then be able to access some of the drive's contents but, annoyingly, not your photos (yet). You need to 'take ownership' of the drive first:

6. Now that you can access your photos, copy them to the other computer (or to something like a USB stick) and then make a back-up copy as well!
