Had same problem - no input. Tried new Video Card. At least Windows tried to start, however when Windows tries to start, goes in circles back to start in Safe Mode Option Screen, try to start in Safe Mode (or any other mode), just goes in circles.

i have similar problems - last night was using the pc, dual monitor setup when bam screen goes black. Rebooted - i can hear the HDD working, but on my monitor it says "No Video Input" so i can't see POST - i hear the windows chime turn on, my keyboard caps lock can be toggled but no display - rebooting did not work, same as above

i've reseated ram, components, tried video card on another pc - worked - tried monitor with another pc - worked
disconnected all power except for boot drive, video and normal motherboard connectors

reset cmos, remove battery,

same effect- i know it is booting, ram test with mobo elicits the right number of beeps
scoured the web for answers, it turns out this seems to be a common problem but no common solution -
only thing i haven't tried is replacing ram

so posting it here in case some of ya might have an idea or two to check out

my system core i7-920, 6GB RAM, ATI4850, Win 7 64 home premium, 400W power supply
