Hi, I'm having problems on a system with a gigabyte MA78GM-US2H and a amd 9850 quad. The computer works fine but after I install symantec I can no longer get the computer to go to sleep, It just reboots and starts up again. When I remove it, the computer can go to sleep again. I have updated all of the drivers and the mobo bios but the problem is still here. Any ideas on what to do next? or maybe is there a free virus program out there I could use instead? I would rather not have to buy something different if I can avoid it. Thanks
