Hello all; For the past several mornings, when clicking my mouse to wake my PC from sleep mode, my screen remains completely black. I can hear the PC start up, the fan running, etc. I can even hear the Windows log on sound when I punch in my password. All power lights are on, but the monitor refuses to display anything, not even a blinking cursor. My keyboard then becomes unresponsive and I'm unable to shut my PC down using the power button. I've had to hard reboot several times by manually switching my surge protector off and on. After getting the expected message that Windows didn't shut down properly, my system then starts up as usual. I have Windows 7 Home Premium (64 bit). My processor is an AMD Athlon II X4 630 and I have 6 GB of RAM. Both my PC and monitor are brand new. I would greatly appreciate any advice. Thank you.
