Hi. I just bought a new graphic card, Nvidia GeForce 8400 GS to replace my old GeForce 210. I installed the hardware like the way it meant to be, and boot up my computer. Everything is running fine, until when it displays the usual windows screen. After that there is no display whatsoever and the monitor indicates that there is no signal. I thought the computer was turned off, but it didn't. It was running fine, just without any display on the monitor.

So how can I install the driver if I can't even see anything? Please help me.

[duh]

Boot into [Only registered and activated users can see links. ], do you see your desktop? If so, you should be able to install drivers.

I can't even see anything even in safe mode. =/

[duh]

Have you tried putting back your old graphics card to see if you can still get into Windows? If you can, try uninstalling your old graphics drivers and also use [Only registered and activated users can see links. ] (tick the NVIDIA - Display option ONLY).

If that still doesn't work, try your new graphics card in a different PC if you can to see if it does the same thing, there's a possibility that it may be broken even though it's brand new.

Thanks. I'll try this method first. I'll inform you the outcome.

It's not working. I've tried the driver sweeper, and the problem still persist.

Thought of the fact that you might've just gotten a defective card out of the box? You tried it in any other computers besides your own to check?

[duh]

Do you have another PC to test if your new card is faulty or not (or know someone that you with a PC to test on)? I can't really think of any else that's not drastic.

As last resort measures, try clearing/resetting your BIOS and if that doesn't work reinstalling Windows. I don't really recommend doing them since it's a complete hassle and usually waste of time.

1. Make sure it is connected to the right videocard, not on the build in videocard when people have that they tend to connect the video socket to that card without them noticing.

2. make sure that you have connected it to the right socket if the videocard has multiple outgoing sockets. just start the computer and test them by switching it between plugs.

3. make sure the videocard is in its socket completely.

4. Try to reset bios to default.

5. New cards tends to have extra energy supply's make sure you have installed that, also newer cards uses alot of energy so make sure your power supply supports that much power make sure you have atleast 400-500 watt.

there is a small chance that it's faulty because it works when you start the computer, it is probably is a human error. if none of this work try to pull out the card and remove the battery for 30 seconds then reinsering the card.

Not necessarily, I've had a broken graphics card that did exactly that - could see the BIOS and POST screen, but blank screen when in Windows (due to the actual hardware trying to kick in). Although Safe Mode should've negated that, but seemingly it didn't, so the problem appears to lie elsewhere.

Also the GeForce 8400 GS is a pretty old card so I'm pretty sure it wouldn't need that much additional power. In fact, from a quick [Only registered and activated users can see links. ], there's a 9 Watt difference, negligible really.
