Black Screen with Question Marks ("?") upon boot-up
New to the forum.
I've been baffled by an issue I've come across recently and seek the advice of some tech gurus.
Yesterday I was playing a game, Bloodline Champions, when all of a sudden my screen went black and my monitor went into standby mode. It was as if my computer went into hibernation mode. However, upon pressing multiple commands it did not wake up and when I pressed the power button it just simply turned off.
Upon turning back on after post, I was presented with a black screen full of question marks in random order. There would be a series of 5 or six followed by several blank spaces, then several more and so on, filling up the entire screen. At this point I figured it was a virus so I reformatting my computer. After I reformatted with Vista x64, I restarted the computer and lo and behold the question marks returned. Granted they don't prevent me from loading windows, but I'm still concerned.
Any thoughts, advice? I'm leaning towards hardware as it continues even after a fresh re-install.
