I've downloaded and installed Revo Uninstaller but I can't see anything called Gigabyte Easy Saver. There are only a few installed items...
Browser Configuration Utility
Easy Tune 6 B10.0521.1
Gigabyte Raid Configurer
NEC Electronics USB 3.0. Host Controller Driver
ON_OFF Charge B10.0427.1
Realtek Ethernet Controller Driver for Windows 7
Realtek High Definition Audio Driver
Smart 6 B10.0422.1
Could any of those be it?
Also, after disabling Driver Verifier, I could load Windows up properly (not in safe-mode) I tried to connect to the internet again to get the original BSOD. I managed to get a picture of it, but this one doesn't seem to have anything about gdrv.sys on it...
Thanks again for your help with this.
