Hello i am new to the forums because i found this website while looking for some answers to my problem. When i'm on my computer playing a game or something, sometimes my screen will go Black and a box will come up and say "No Signal". My progams that i was running before the screen goes black will crash.(i know because i will be playing music and when my screen goes black it will stop playing). I have to hold my reset button on my computer to get it to come back up. It didnt bother me at first but now it is happening alot more lately. I don't know what it could be, so if any answers would help, and if it is a download like a driver please give me a link, i think it might be my video card but im not sure, this is my vid card: NVIDIA GeForce 7800 GT thanks in advance, Jake.
