Laptop issue. Please help.?

Okay, so recently my laptop stopped working correctly. Microsoft messed around with it and made it worse. Geek Squad told me windows 7 was probably corrupt and that I needed to purchase Toshiba Recovery disks. I did so and was finally able to get on my laptop again. I lost everything but saved the important things like all my movies/tv shows, music, files, etc. When putting all that data back on I got my movie/tv show folder in alright and was still able to go on everything. I started transferring my music folder on and it went all funky. It started doing what it did in the very beginning. Not opening applications, loading things very slowly, all programs not responding, not connecting to the internet. So I went onto safe mode and deleted my music folder (or what was in it because the transfer was not complete) and I was able to get on fine. Is my music library corrupting my laptop?
