Hp pavilion elite m9690a turns off input signal randomly after boot up

Question

I have a pavilion elite m9690 running off of windows vista which recently (there have been no changes) begun switching off all input signals to the screen. Although the pc activation light and the pc are still on it then does not respond to the mouse, keyboard or switching source from hdmi to VGA leaving no input signals to the screen. When turned off then on again it regains input signal to the screen. The timing can be during startup or as late as 15 minutes of operation. I have plugged my l laptop into the screen and this never switches off on hdmi or VGA. I have made no changes to the pc but had some issues with heat a month ago.

I am having the same problem as Avro500! My computer is the hp pavillon desktop model a6863w. The computer freezes then the keyboard and mouse will not respond and the only thing I can do is shut it down and even then I have to hold the pwer button about 10 sec before it shuts off! I have unplugged all external devices like you told avro500 to do and I did finally get it started but the computer still freezes and it is doing it more often as time goes by! I even paid HP support the $100 dollars (or around that amount) to fix it but it keep happening even after they worked on it but it was after the 7 days or what ever their policy is! They downloaded some security suites and ran their scans! They left Advanced system care, ccleaner and superantispyware on my computer and I was just wondering if they could be conflicting with my paid norton internet security? I have become very flustrated because first off I paid a lot of money for this computer and it's not even 2 years old yet and I also have paid HP a lot of money to fix it and all the guy from India could say to me was "I have been working on this computer and it hasn't froze up so the problem must be fixed!" Well it's not!! and I don't know enough to fix it myself so thats why I paid you a hundred dollars to do it for me! haha thanks for any help!
you have a different model PC. Don't be a thread hijacker. Start your own thread.
