Assuming that you've not actually deleted your photos (but simply misplaced them), run a search for *.jpg . That will find all files on your computer that end with a 'jpg' file extension.
You'll probably then see some options to click on, such as 'Documents' and 'Photos'. Try the 'Photos' one first. If that doesn't help, then repeat the search and try 'Documents' (and any other options you might see).
If you find one of your pictures, RIGHT-click on it and select 'Open file location'. That will take you to the folder where it's stored, enabling you to look in the Windows Explorer address bar to see where that folder actually is.
If you've actually deleted your images, and then take your computer into a repair shop, all they'll do is to to run some recovery software, which you can do yourself for free anyway. Download, install and run Recuva:

(There's a small risk that the download might use the same bit of space on your hard drive that your photos were on but, with the massive size of hard drives these days, it's probably a risk that can be ignored).
