Got myself a new Videocard (Winfast PX-8800 Nvidia) only to discover that the screen wont "boot up" properly. First the led indicator turns green like normal then it says "power saving mode" and it turns yellow. Then it turns green again but there's no image what so ever. I can still hear that windows boots up ok if i let it boot all the way. Tried both monitor ports on the card. +12v cable is connected. Flashed the BIOS but no luck. My comp works perfectly with my old card PNY Nvidia 7900GT.
I took my new videocard to my friend who has the same one and it worked there?! Now, my friend has a CRT 19" screen and i have a 19" TFT. I read through the motherboard manual and doesnt seem like theres any jumpers i shall move or anything considering mother board supports SLI. (M2N-Plus SLI Vista Edition, Nforce Nvidia 500).
I'm starting to suspect it's my motherboard that is defect? Any suggestions? Please help, this is very frustrating!

Thanks for all the answers! But problem is i dont even see the BIOS boot up or anything. The screen is black no matter what even when it boots up in windows. But the led indicator on monitor is green sometimes. Weird.... but ok ill try to do as you guys say by uninstalling my old gfx card and then see what happens =) Thx again and wish me good luck =)

Yeah, check your power supply first and make sure its got enough juice for the new card but mostlikely its that you need to unistall the old graphics card driver then install the new card software off the disk. You also might check the BIOS and make sure it is set to auto detect the graphics output. Its just a trial and error deal when installing hardware.

You have a lcd monitor and you're settings in windows do not match those of the video card because the new video card drivers have not been installed. You will have to boot into safe mode (hit f8 repeatedly when you first power up until the boot menu appears). Once in safe mode uninstall the old video card then install the drivers for the new card. Adjust the resolution setting to match the native setting of your monitor.
What clued me in what the fact that it worked with a CRT but not with your LCD. I bet if you borrowed your friends CRT monitor your computer would boot up with the new video card.

I'm assuming you removed the old video drivers first? If not then boot into vga mode via the bios and remove the old video card drives. Reboot and allow windows to load in vga mode, install the video card drivers from the cd that came with the card and you should be good. Also your power supply may not be powerful enough, he is correct. I installed an 850 watt thermaltake to support my sli.

The same problem occurred to me when I installed my Nvidia 7600gs. I think the problem could be that your previous resolution settings are not supported by Nvidia 8800 so the new video card is not able to render the image so you should reinstall you old video card then adjust the resolution to something mutually compatible for both video cards such as 1240x1024 and then install nvidia 8800.

You probably need to make a change in the BIOS. You will need to set the video so that it looks to the PCI-E slot and not the AGP slot. So reconnect your monitor to the old card or onboard connector, do the BIOS changes and then reconnect to the new card. After you get the new card to connect to your monitor, install the drivers for the new card.

Have you tried disabling the old graphic card drivers or uninstalling them?
Those are sometimes the case.
Sometimes it might be the power supply, but maybe you know more about your computer than me, good luck.

hi well if your computer screen shows you your windows screen after starting the computer then go to device manager and see whether your disply adapter is recognized there or not if it is then there is no issues with the OS and its your adapter settings and if it is not getting detected then try installng the drivers for your adapter.........and if it doesnt resolve the issue remove the card and use the older one and go to the BIOS and change the settings and then shut down the computer and put the new card back in and then restart and check whether it works or not !!

Not enough amperage on +12V line ? you might try your friend's power supply unit on your board.
The others are right too.. the latest cards often need the latest drivers to work well.

most probably, delete the old drivers for the old video card and install the new driver of the new video card ^_^
