 I recently bought a big screen TV to use as the monitor for my computer. For some reason I can't get my computer to boot when the TV is plugged in via HDMI. My previous monitor was connected via DVI and I never had any issues. Any time the TV is connected my computer won't boot. If I plug in the TV after the PC boots everything is fine. But if the TV is plugged in it won't and if I unplug the TV after it has tried to boot it still won't boot until I push the power button to turn it off and then turn it back on again. The PC doesn't seem to be getting very far in the boot process. Simply tapping the power button immediately turns it off. My PC has a 980TI if that makes a difference. I have tried both passive and active HDMI cables and both have this problem. At first I tried multiple HDMI cables and most it wouldn't boot with, but then I did find one that it did boot with, but then it mysteriously stopped booting one day. That same cable still works once the PC has booted. I just don't understand how the HDMI cable could affect whether a PC boots or not or how an individual cable could go from working to not working. Any ideas what could be causing this?
