Video Card Compatibility / Installation Issues?

Hi there, I have just bought an Nvidia GTS 450 and I had hoped to install it into my Pegatron M2N78-LA motherboard (it has an integrated Nvidia Geforce 9100), but whenever I try booting up my computer with the card in, my monitor stays idle and my computer boots for about a minute before it crashes.



Before installing my new card, I went into the device manager and disabled my integrated chip in safemode, powered off my system, and then popped my card in.



A word of note: the first time i tried installing my new Nvidia, I accidentally chose to Uninstall the integrated card on the Device Manager rather than disabling it, but the next time I booted my system without my new card in it, it automatically downloaded drivers for the integrated card and seemingly works fine.



I've narrowed my problem down to two possible options:

1. My new GTS 450 is incompatible with my motherboard

2. The drivers for my new hardware are all f*cked up



If you could give me any advice at all that may help, I would really appreciate it! Thanks in advance!|||You only need an available SLOT..

There really is no compatibility..except that some things you may attempt in a graphics environment--will require hardware..

You need to remove the Graphics Card..

You need to re-install your integrated video card..

Once that's completed..

Do a Restart and TAP(repeatedly)..F-2..

You will OPEN..the System Set Up Program..

Now look for your Video Adapter..(use your ARROW-Keys)<<-->>

To flip thru the pages of the System Set Up Program..

The ARROW Keys will also move your CURSOR for you---up and down..

===

OK..find the Video Adapter and Choose--AUTO..

..this will allow the computer to choose the BEST..video solution..

If your Video Card is installed in the SLOT--it will be chosen..

..if NOT..the integrated video card will be chosen..

This can be a helpful--setting..later you can try the selection for the installed video card alone..

===

OK...you have used the Setting for AUTO--now use the SAVE Changes--and--EXIT..keystroke..

Be very careful that you have NOT--changed any other setting--be very careful//

===

Shut Down the PC..

Install the NEW Video Card..

Connect the Monitor..

..and Start your PC..

You should have normal operation..

You reach your desktop--let all the drivers LOAD..

Wait about 5-minutes..

Then use the CD that was delivered with your NEW Video Card..

Register the Product..

..then go to the MFG. website for the latest drivers.
