Installed new video card and no signal problem. I've upgraded my ram from 512 mb to 2 gb. And went to turn on computer I got a no signal from my monitor. The compute boots up and everything. So I replaced the old g-force 7300gs card with a g-force gt 610. And I am still getting no signal. So I even went as far as putting the old ram back in. And switching monitors and still nothing. And the onboard video does not work either. Any ideas.

We need to know the make and model of your motherboard, and the spec's of your memory (the 2GB) and the video card, please.

Did you handle the cards and memory by their plastic edges and use an anti-static wrist strap, or some other means of ESD safety measure?

If you remove the video card and any memory (so that there is no memory fitted at all) and then reconnect the power cord and turn on the PC you should hear a beep error. That's a good sign. If you don't get any beep errors then there could be a fault with the motherboard.

Disconnect your PC from the power and press the PC power button. Being aware of ESD, fit the 512MB, but not any of the video cards. Using the onboard video, now reconnect the power and turn it on.

If that works then follow the process of disconnecting the power, etc, as you did above. Now fit your old video card. Power up, and let us know what happens. Hopefully it should work.

We need to know the make and model of your motherboard, and the spec's of your memory (the 2GB) and the video card, please.

Mike, thanks for all of this info. Just one more thing, please. Your reference to Ati ixp 400, is for the onboard video chipset and not the model of your motherboard.

If you don't still have your manuals, etc, then you will very likely see the model number on the motherboard itself. It won't be on any of the chips you see, it'll be on the motherboard. For example it may be written in large white letters and look similar to this "K8AE-LM", but with different letters and numbers.

RS480M is what says on the motherboard.

If the information you have given me is correct, then please note what your motherboard manual says and compare this with the spec of your video card.

Your motherboard manual says:

One PCI Express x16 slot (supports PCI Express Bus specification v1.0a compliant)
Read these specifications also.

nVidia GeForce GT 610 Spec:

Bus Support: PCI Express 2.0

Could you download that manual and just have a look at the images and other data to confirm that we have the motherboard details correct, please.

If the information you have provided is correct then it appears that your new video card is not compatible with this motherboard. Whether a PCI Express 2.0 card is compatible with a motherboard that uses PCI Express 1.0a isn't clear, but doesn't look promising considering your experience here.

Sorry, while writing my reply I accidently tapped the 'down vote' button. As soon as I realised this I removed it. (I use a tablet)

Yea the info on the motherboard is correct. Which from what I understand is that my video card the GeForce gt 610 does not work with the motherboard I have. So is there a video card that is supported by my motherboard and that is a good video card?

This is only my opinion, but while you're making all of these upgrades, have you considered upgrading your motherboard too? You would need to purchase something that would accept your CPU, memory, and video card. (PCI Express 2.0)

A number of systems will default to the onboard NIC unless you disable it in the BIOS, otherwise your add-in card may not work. Plug the display into the on-board port and boot into the BIOS to see if that is the case.

This is a graphics card problem. The onboard NIC will have absolutely nothing to do with it!
