Computer is on, monitor is blank

Hello, I have a Presario sr1710nx desktop, when i turn on the computer, my monitor turns on, but inmediately the light turns yellow. On the pc, the fan is running, power light is green, except the indicator light is yellow. I disconnected the monitor and tried it on my laptop, it works fine. So my question is, could it be the video card that needs to be replaced, or is it a motherboard issue. Right before this issue, i got the blue screen, if that can shed some light. If any of you can walk thru what i need to do, that would awesome.

Thanks in advance
