hello all.
I don't know if I have posted this on the correct forum, but it's all visual isn't it.
Ok, My Daewoo flat screen monitor has started to just go blank after a few hours of working on the p.c.
It goes black, and then a message appears saying "No Signal", ten it turns off.
I have plugged the monitor to my laptop and it worked ok.
What could be the problem?
Is it a graphics card problem? I have an Nvidia 128mb agp card,
Sometimes I can work for hours until this happens, however a month ago the problem repeated itself quicker and quicker happening all the time. I reformatted the p.c and the problem went away for a month, but now it's back. Arrrghhhhh.
Please help.
Do I need a new p.c?

Thanks all.
