It's difficult to troubleshoot a problem like that via list, but have you tried a different monitor? If you have and have not had the problem it would of course most likely be your G810. CRT monitors and power supplies are the least reliable parts of a computer system. If you have tried a different display and the problem remains, then if possible try a different video card. If neither resolve the problem, then it is a motherboard or other issue that will require a service call.
