no display after video card install

by 289falcon / April 2, 2011 1:27 AM PDT

Hi, my daughter has an hp m7760n running Windows 7 (was Vista). We tried installing a new video card thinking we were following the directions. We disabled the onboard video and installed the card, however it also said that we needed to change the BIOS to change the PCI express slot from AGB to PCI E and we did not do that. Now we have no video on the monitor to make any changes or to enable onboard video. Do you have any suggestions on how to resolve this issue and is all of the previous information correct or was there another step that was done/not done in the process that caused this problem? If at all we just need to know how to reboot the computer back to a point where the onboard video is enabled again so we can see what we're doing.

For a further question, assuming this can be easily resolved, does the onboard NEED to be turned off or will the computer immediately pick up the new hardware (the video card in this case) and you can choose which to use and which to disable from there?

Appreciate the help and hopefully someone knows what's up.

Is Power supply compatiable with new video card
by Oceantiger65 / May 2, 2011 10:45 AM PDT

If disabliing the on board video and changing bios to PCi, did you check to see if your Power Supply was compatiable with the video card you are putting in your computer( 450 watts minimum). The new video cards have 3D/HD and multi video monitor capabilities and other graphic accelerators and no one ever thinks to check the power supply to see if can run all of these extra software and hardware. If you type in the search videos section on you can watch the video on how to install video cards and power supplies. Sometimes the video cards are just not compatiable with the computer and you can go to sites like and check and see what video card will work with your system. Also, check and to find cheap compatiables, as well.
I hope this thread wont discourage you from trying to continue DIY computer hardware and software installations.
It is not difficult just time comsuming.

check power supply

I forgot to add after you remove the video card, turn on computer and go to my computer on the desktop and right click and click on properties, then click on hardware, then click on device manager, then click on plus sign next to display adaptors, this the name of your on-board video. right click on your on-board video and reenable your video and then you are good to go till you try to change it again. Always disable on board video to enable any video card.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
