i disconnected dvi to hdmi adaptor and cable to hdtv and all is well. they worked alright for a few hrs. maybe the resolution was a problem. thanks to any of you moderators who were scratching your heads and formulating a reply.
This pc won't boot. It starts to boot and gets to screen with blue background and INVENT logo. Options are setup, boot menu, system recovery. i can access the setup and the boot menu but F10 key seems to not function. I cannot get to safe mode as hitting F8 does not bring it up. i tried the recover dvds but i get to the place where i can choose R for normal recovery and the screen goes black forever with no furthter screen activity. I was messing with the inputs on my HD tv [being used for a monitor] when this occured. i attached or detached an input [don't remember which one]. i was getting dual screen output via dvi and s-video before the problem. now only dvi will display. help!!!
