LCD TV backlight going out after getting new graphics card.

Hi there. I upgraded my graphics card roughly two weeks ago. I went from a GeForce 6600 FX 128 mb to a GeForce 9500 GT. With the 6600 I used a DVI to HDMI cable to run my 32 inch LCD TV as a computer monitor. It worked without any problems for 6 months, however now with the new graphics card I'm having problems. Randomly while using the computer the backlight for the TV will turn off. When I unplug the TV from the computer though it goes back to normal, and while the backlight is off I can't change channels, go to the menu, or anything. I tried using a standard HDMI cable with the new card, but the problem persists. I thought perhaps the card was over-heating however upon reseting the computer it runs fine for a full day or so. I have the latest drivers for the card, so I'm uncertain of what it could be.

*Note, I did upgrade the power supply for the new card, I use a 650 Watt at 80% efficiency so I doubt the power supply is the issue*

    It works fine with the old graphics card oddly enough. Also the new card, the GeForce 9500 GT, supports the LCD TV so it's not compatibility issues, I appreciate your time and hope you can help.

Here is a list of compatible GeForce cards for this PC's.
GeForce 6 Series - (GeForce 6200, GeForce 6600GT, GeForce 6600 and GeForce 6600 LE)
GeForce FX Series - (GeForce FX 5950 Ultra, GeForce FX 5900 Ultra, GeForce FX 5900, GeForce FX 5900 XT, GeForce, GeForce FX 5700 Ultra, GeForce FX 5700, GeForce FX 5700LE, GeForce FX 5200 Ultra, GeForce FX 5200 and GeForce FX 5500)

You should already have a GeForce FX5200 so better than that is the 6600 and 6600GT.

Need graphic card upgrade for Dell Dimension 4500 w/ pixel shader

This is an older machine that has a 4x AGP port for graphics cards. The good news is that cards for this slot are cheap...usually in the 30-50 dollar range. The downside is that you wont get the greatest performance out of them. I would recommend going with a Geforce FX 5200.

I own a Dell Inspiron 531S. I'd like to get a new graphics card. I currently have a NVIDIA GeForce 6150SE nForce 430. I don't want to spend too much for this but I'd like to run my Second Life game with...

When you install a new video card you must disable the onboard video card by going into the bios setup. Below I have listed the requirements of Second life game. e 531 does come with PCI-E slots so make sure you buy a VIDEO card with PCI-E Walmart sells some pretty decent priced Graphics cards. pretty much any pci-e card you buy new in walmart these days will be fine for this game.

PC Minimum System Recommendations:

* Internet Connection*: Cable or DSL

* Computer Processor: 1.6GHz Pentium 4 or Athlon 2000+ or better

* Computer Memory: 512MB or better

* Video/Graphics Card**:
o nVidia GeForce FX 5600, GeForce 6600, or better
o OR ATI Radeon 9600, X600, or better

Having Problem with my GeForce FX 5700 Graphic Card

The card may be overheating and switching to lower DPI to save on the power consumption and heat. Try using a diagnostic utility to check the card temperature. Also, check the heatsink/fan to make sure that it is properly seated on the card.
