I recently downgraded from Windows 8 to Windows 7 Home Premium on my G74SX. I used the OEM license that followed the computer. I've updated all drivers, but when I start the computer from sleep mode I get a bluescreen and my computer turns itself off. This always happens when it has been in hibernation mode for a while. I've never had any problems with this this before, even when I had Windows 7 some time ago with almost the same drivers.
The error code I get after the bluescreens is:
0x000000f4 (0x0000000000000003, 0xfffffa800a1e0060, 0xfffffa800a1e0340, 0xfffff800031e3460)
