No signal from new graphics card- Please Help!!!

Did you plug the power pins on the video card?

try both the dvi slots. And make sure nothing got moved around while u were installing the card ex check ram to see if its seated properly. oh ya make sure the dvi/vga connector doesn't have any broken pins.

bad video card? RMA.....

When the 4850 is installed, do you get a signal from the onboard video card?

If you do, go into the bios and look for a setting that will allow you to disable the onboard and perhaps switch to PCIe.

I'm only suggesting this because I thought that maybe the 8600 somehow tells the motherboard to shut off the onboard but the 4850 doesn't....worth a shot?

I thought the card at first was bad, so I RMA'd it, and this is the second one so I doubt its faulty.

With the 4850 installed, I do get video from the onboard card, I went into my bios and there is no option to shut off onboard video.

However, with my 8600gt installed, there is no video from the onboard card? What does that mean? It seems that it switches to the onboard video if I take my card out

and thank you for the replies everybody!!

you mean take battery out and put it back in? no, but are you supposed to do that after you put the new card in or before you put it in

could you list system specs, i just want to know what brand the psu is?

sure, here is the link to my ps:

I think it is a problem w/ the onboard video. For some reason, when I put the 4850 in, it enables onboard video but when I put my 8600gt in, onboard video is disabled and I get a signal from the gpu. This is really weird, anybody else got any ideas?

And I think my psu is good enough, I am running a processor that doesn't take much power, one optical drive, one hard drive, and 3 120mm fans

and thank you for replies

Since you RMA's your first video card, it is probably due to 1) Your power supply not providing enough power to your video card. or 2) Your bios and/or motherboard somehow does not like this video card. What is the model of the motherboard and the CPU you have?

According to their website, their minimum is a 450 watt power supply. I don't know how your power supply is working, but it might not be providing enough power to the video card. I would try to unplug the power from fans, dvd rom, and the hard drive to see if it works or not.

I don't think it's his PSU.
Sure Rosewill are far (FAR) from the greatest, but that specific PSU's got good reviews, is SLI certified and certainly has enough juice to run the card.
Plus, one of the reviewers has a 4850 and it powers it just fine according to him.

I'd do what helios suggested.
Disable the onboard video from the BIOS, there should be an option there.
We can guide to where it is if you give us the name and model of your motherboard.
Also, as previously suggested, try clearing the CMOS.

*EDIT* Nevermind, Sorry I was typing while you posted That Bios is very limited and it is set to go to the 4850 first....

Insufficient power should not be a consideration at this time. I have that PSU in my secondary machine powering an 8800GT.

There are only 3 things I can think of left to try.

1) Clear the cmos using the button on the motherboard or by taking out the battery for 30 minutes. *EDIT* (Computer should be off)

2) Boot windows using the 8600 and update the bios to a newer version, because they may have released a bios update to work with the new ati cards. ( I think this is your best bet!!!)

3) may have to get a new motherboard.

doesn't matter just make sure the 4850 is in when you replace the battery and turn on the comuter

It wouldn't hurt to get a few more suggestions before buying something.

I tried to think of every possible problem, but I am only one person and could very well have missed something.

In any case, Good Luck with you card!
