Hello, I need nVidia GeForce 7400 graphic chipset for Sony Vaio All-In-One desktop Motherboard VGC-LA2. Unless other graphic card or chipset can be used. Problem is power-on and screen goes-off. Press Monitor-on switch screen comes-on and in 5secs off again. After warm screen sometimes screen stays on for a while or longer. same repeat on/off.. According to sony web site seems nVidia GeForce 7400 graphich chipset problem so advise solution and cost for this.

OK...I have the same computer, with a different problem, but maybe from the same cause.
My computer it's doing like this: when I started in the morning, pushing the start on/off switch (the screen it's staying black all the time) after just 2 seconds I can hear one long beep and two shorts....then, silence....no Vaio logo, no nothing.
I tried, of course F8, F2 and some other combination....
As I read on the internet it's something wrong about the video card.
Any idea please?
