Bluehair wrote: When your screen is black, is it really black or can you still see a faint image on it (if yes, your lcd inverter may be faulty; this component powers up your lcd's backlight)?

Bluehair wrote:I suggest you plug in an external monitor and check whether the same problem occurs. If not, your graphics card is probably not involved. It may be your video cable that has gotten loose somehow.
Bluehair wrote:But if you say that running on the battery or downcloking the motherboard/gpu speed (what the silent mode does) solves the issue, it may be the sign of an overheating problem. You should watch the temperature of your CPU/GPU/HDD. These programs can help you for that:
- CPU and HHD: Mobile Meter 0.3.1.0, Notebook Hardware Control
- GPU : NVIDIA Control Panel
The presence of dust in the system fan or in the rear heatsink can degrade heat dissipation and cause unpredictable running issues.

If you have kept the original video BIOS (v39.49), then you won't be able to use any ForceWare drivers above version 7x.xx. I have written a tutorial sometime ago about upgrading to the BIOS that fixes that:

And just for your information, I currently have ForceWare 95.97 installed (for several months) -- they work just fine.

Bluehair wrote:Besides, when your screen is black can you see something if you aim a flashlight straight on it? It could be your inverter board that is malfunctioning -- this is a high voltage DC->AC transformer whose only role is to power the lcd's CCFL (i.e. its backlight, Cold Cathode Fluorescence Light).

That's all I can do I'm afraid :/
