Windows 7: Gigabyte ATI Radeon HD7770 Crash Screen

Gigabyte ATI Radeon HD7770 Crash Screen

I'm having problems with the Gigabyte ATI Radeon HD7770 OC Edition graphics card. The graphics card will occasionally crash to a grey or white screen and I will not be able to do anything. No error messages are given to me at any time during a reboot of the system. I have enabled "Triple Buffer" in ATI Catalyst Control Center. I have also enabled AMD Overdrive and overclocked the device.

Default GPU Clock: 1100 MHz
Overclock GPU Clock: 1110 MHz
Default Memory Clock: 1250 MHz
Overlock Memory Clock: 1275 MHz

Nothing else has been changed. I have no idea what could cause it to crash and what's even more frustrating is that it also crashed during PC idle time (i.e. When I leave it to download something). Could any one provide me with some help and I have also contacted the seller for a possible replacement.

Do you have the most recent drivers installed? Also, have you altered any voltages?

Yes I have installed the latest driver provided by AMD. And no I have not touched any power settings in the Catalyst Control Center neither in the UEFI.
