Laptop randomly bluescreening

My laptop has been suffering from random BSODs lately and I, as any normal computer user, would want to get them fixed. Windows created dump files from these bluescreens, so I had to use Google to find a program that can open .DMP files. I found this guide and it had a link to .iso image download of Debugging Tools For Windows on Microsoft’s download site. That disk image had a program called WinDbg and I used that to open the DMP files. Both memory dumps had ”VISTA_DRIVER_FAULT” written in them. That pointed me towards drivers that might be either out-dated or corrupt. After this I remembered that i had VLC open when these bluescreens happened. This lead me to believe either my sound or graphics card drivers are bad. I updated ATI drivers and re-installed sound drivers. I’m hoping this solves my problems.

My laptop specs are following:
Windows 7 Professional 64bit SP1
Laptop model: HP Pavilion DV7-3013eo
