As the title says, once windows XP boots I loose video signal to both my monitors, same results in safe mode as well. I was using my computer normally and then left it for a few minutes, while I was gone it seemed to have restarted itself (the backlight on my keyboard was turned on, which only happens if I turn it on myself or if my system is restarted) and both my monitors showed no video feed. Now whenever I restart it, or completely turn it off and back on, it seems to load windows normally, but as soon as it's finished the video feed cuts out
I'm running an ati 5770.
Thanks for any help, and please let me know what other details I can give.
