Hello buddy,

just try one thing and let me know what is does because this appears to be a curious problem that you have.

so try using a different power supply unit and then see what it does?

see you

I have been having the same problem, Last night there was a Brown out at my house (the lights flickered on and off really quick in the house, but didnt go completely out). Later on when i go to my computer I turn on my computer and it turns on fine, the computer screen has power, but it says no signal, and the normal blue light(when its on and working) turns orange (the standby color). Does this mean that my Graphics card doesnt work? or is there something else that i missed? I checked my graphics card and it appears that the fan isnt spinning. So my guess is that it burned out. My predicament is that i had it on a power strip with a surge protector thing on it. Shouldnt that have stopped it from getting messed up like that?
