I have an ATI Radeon 5450 in my HTPC. I'm having a couple of problems. First, the computer seems to start up on its own from standby at random times and for no reason. I have disabled the "Allow device to wake computer up" box from every USB / LAN device, but still it persists.

More importantly, the computer will not display anything to my TV unless the TV is on before the computer is turned on. If the computer wakes itself from standby while the TV is off, I can't turn the TV on and use the computer - I have to hard reset the computer, with the TV on, before anything is displayed. Any ideas?
