Hi guys i just got my new graphic card which is a Radeon HD 4550 from gigabyte.

I have a dell 8400 and when i connect everything and start up the computer it all shows green back on the computer. but the monitor won't respond. why?
Its either self test features check 1, 2 or something about power saving mode. try to click any button or move the mouse. OR i click the button that shut down and open the screen it's green for only 3 seconds, the screen is black and it turns yellow.

What should i do?!?!

forgot to say that i had a nvidia 6800GT which has been "burned" somehow and have now changed to an ATI Radeon hd 4550 from gigabyte

With everything powered off, make sure your new GPU is firmly installed into the motherboard. Also, verify that both ends (PC/GPU and monitor) of your video cable are securely fastened (if using VGA of DVI, screw in the retaining screws finger tight). Then try again. Good luck!

It might just be a bad card...

Prepared to to experience a significant performance decrease with that 4550. Return it now and just get something better; assuming AGP is your slot go with 4670.

First< I don't recommend that you plug/unplug anything while the system is powered on. That is the fastest way to zap something.

Does the video card/monitor display properly with a VGA cable? Or, does it do the same thing as the DVI cable?

i dont know.. i dont have any VGA cables only DVI.

i've now noticed a new thing. Back on the computer there is diagnostic lights they all turn green just in a second, but after a while it make noises and turns to A C green and BC to yellow then it turns green again.. and it will repeat.
Another thing is that when i push the power button on the computer it shuw downs immediately. normally you have to hold the button for like 5 second but it shut down just when i click it.

That means that the system hasn't made it past the BIOS spalsh screen. It may be stuck in Diagnostics mode.

What happened to the original video card? Did the system ever work after the 6800 was damaged/removed?

I looked at your Dell forum thread and I agree that your previous video card was the likely problem. BTW, when you installed the 4550, was the computer powered off and the power cable disconnected?

BTW, even new GPUs (video cards) can be defective.

Yes ofcourse. its too dangerous to plug in the cables while you remove and putting the card.

Good for you. You did it correctly. You would be surprised at the things people do when they aren't sure about how to do something.

I suggest you go through the process of removing and then reinstalling your new 4550 video card to make sure it is firmly installed.

Physically remove the video card and then re-insert like you did before.

Do you have access to another working video card that you could swap into the system for troubleshooting?

If not (or you don't have access to another computer that you could install your 4550 into), then RMA the 4550.

However, since your previous video card flamed out, it is possible that your system was damaged as well.

Just something to consider.

If you can't verify that the new video card is good, assume it is bad and return it (exchange).

Do you have access to another system to use for troubleshooting? BTW, a technician couldn't verify anything unless he/she put in a working video card and got the system to operate normally. It is entirely possible that the PCI-E slot you are using to install the video card is defective. That is why I am asking about access to another system. Understand?

Actually buying a defective item happens from time to time. While fairly rare, it does happen.

BTW, you still haven't said if you have access to another system for troubleshooting. I assume the answer is "NO".

COL. i have a question. when i had my geforce 6800gt. i had to connect the 6 pins to the graphic card which is inside the computer. The radeon hd 4550 didnt have one. Maybe that's the problem?

The HD4550 doesn't require additional external power. It gets all it needs via the PCI-E port.

i see. But thank you for all your help. I called them and they are sending me new one in a couple of days. i let you know how that works out.

Sorry for double post.

But please answer one last question. you said something about BIOS Splash.. how can i fix that? because when i click the power button it shuts down immediately.

Well, hopefully when you get the new GPU it will fix the boot (or lack thereof) problem. Since you aren't getting beyond the splash screen and can power off immediately by pressing the power button, it means your system isn't going past the initial BIOS diagnostics routines.

Until you have a good GPU to install, you really can't do anything.

So this new graphic card they are sending, if its working should it work around the BIOS?

If the motherboard isn't damaged (or some other component), then yes. You should be able to get beyond the tyipcal startup process.
