Not able to install graphic card

First thing I would try is to unplug the system, install the graphics card, and then clear the CMOS. If it comes up after this, go into BIOS immediately and set to Optimized Defaults. Set any BIOS settings telling it to look at the add-on card before the integrated graphics - or leave on Auto.

Reboot and install Windows drivers.

Once windows loads, it will automatically detect the new graphics card. It may install the driver for that automatically and correctly. Regardless, after it completes, run the CD or drivers that came with the card.

I think reason behind this is intel graphic media accelerator, which i am unable to uninstall.
It comes back after every boot up.
Looking fro more suggestions.
Thanks

yes tried this and it is not working, and yes i am using graphic card vga port.
Anymore suggestion please.
Thanks

try go to safe mode (f8) to uninstall or disable your intel vga driver.

Yes, this is what you should do. Also if you have a motherboard manual, you should check for any other settings that may need to be changed to disable the onboard graphics.
If you are still worried about the drivers, you could enter safe mode to delete, however I wouldn't recommend this as your chipset or northbridge may need some of those drivers.

So, the monitor does display properly before Windows starts to load?

Do the Safe Mode - press F8 repeatedly as POST ends and before Windows begins. If the display works in Safe Mode and you can't get it working despite anything you do, then back up the data in Safe Mode and re-install Windows from scratch.

Set The bios to PEG, the issues is that i hear all the sounds of windows booting, i even see microsoft logo running with ati 4650 card ( no display with 7600 gt though)
Even in Safe mode if i uninstall intel media graphic accelerator it comes back the moment i boot it to normally.
Still going to try few more settings.
I really do not want to format windows as that i take as a complete defeat :_(
So more solutions will be appreciated.
Thanks

Providing more info,
Consider this
That i do not have installed my graphic card's driver.
Now i conect my graphic card in PCI-E slot and then connect to my graphic card's VGA port and boot windows i get display. Now i install driver of graphic card and after instalation when it asks for reboot........there is where problem comes, windows boot but no display.
Please do not want to format windows any help to find the casue of this issue will be greatly appreciated.
Thanks

Yes did this, disabled it from device manager.
The problem always come at reboot
Consider this ( IMGA disabled)
Now i insert my card, install driver, it asked for reboot, if i do not reboot and just enable disable this new ati driver from display adapter everything works fine, ie playing game and all that with good 60 fps.
BUT the moment i restart ( as i have to ) screen goes blank.......
I seriously do not want to format window but honestly tell me what am i missing
Thanks

Yes IMGA is disabled even after reboot.
Now interesting thing is that when i install the graphic card and its driver and then go in to device manager and enable disable this ati driver i am able to play game ( all this without reboot) but the moment i reboot there is no display though windows boot fine. Just no display.
I have disabled all in startup tab via msconfig.
Please let me know if something strikes you :-(
Thanks

Display available at VGA only( when cards drivers are not installed ) not at dvi port.
btw if something is out of resolution then i get CRT message of out of requency. But this is not the case here

I am still working on it so guys if possible then more suggestions please/

Again, look in Add/Remove Software for anything related - remove it. Delete the folder the IMGA is installed in. Look at the details of the IMGA driver and locate ALL copies of that file on your computer and delete it - it won't be able to install itself again.

In Safe Mode, you should be able to delete any files you find.

Yes, no drivers of any kind sounds good. I install my GPU drivers manually and I rarely install anything by loading the CD/DVD. When I need a driver, I point to the location in my \Master folder where I copied the CD and poke around till I find it. I don't let Windows connect EVER to the internet for drivers.

Which of these items in your system are new? Just the graphics card? Might be time to give up on it.

Card is working fine with other machine with vga output.
i am doubting motherboard issue after aaaaall this.
Thanks

If you replace the board, I'd get a different model. Might be some issue with the cards and that board - unlikely as it seems. Let's hope it was just a bad board.

Heck, don't feel bad. At least you didn't have to suffer alone, we were right there with ya. Errrr....

Hopefully, they'll replace your board rather than sending it back. Even with the same model of MB, you may find the issues solved.
