I have a HTPC that I just built. Recently I opted to go with Cablecard to save some money as well as better versatility over the regular DVRs.
Anyhow, everything is working fine, except when I let the computer to be on and I turn off the TV, If I come back after a while, I can not see the screen anymore. It is black screen. I know the computer is working but it's like no signal comes to the TV from the computer to turn it on.
I have a ATI Radeon HD 5450 graphic card with the latest software from AMD. Windows 7 32 bit is up to date as well. Can anyone advice me what seems to be the issue and how to resolve it?
