Monitor blank.

[amruth kiran]

I have an acer x 173 lcd monitor. 2 days ago when i booted my pc. The screen showed ' no signal' this happene before so i removed the graphics card and connected it to the default mobo settings , it worked fine. Then i switched off, and replaced the graphics card. It worked! Now after trying this it shows the same error. My technique is not working.
P.s. Now i have oc'ed my gpu. Is that the problem. I even tweaked the cpu fan settings. Please suggest something.

The port that connects the GPU to the monitor might be at fault. Also please post which GPU and PSU do you have?

Nvidia 9400gt and a mercury 400w
