Recently i upgraded my video card to a NVIDIA 9500GT
A technecian put in and installed my new video card for me.
It worked great i was able to play games on high detail for the first time until it froze and i had to reset my computer.
From there it kept coming up with a blank screen and "No signal detected"

I tried changing the monitor cable to a different input which works but the video card works no where near as well when its connected to the output closer to the video card ( im not very good with knowledge of computers)
Ive tried pulling the video card out and putting it back in.
I definatly know that the cord that connects to the monitor has nothing wrong with it because ive tried two different cords.
When i go manage in my computer and go to display it still says my old video card is connected not my new one :S
please help me it is very annoying
