A user dropped of the above HP along with an HPw1907 flat sceen monitor saying there was no video output. Hooked the monitor up to my laptop & another desktop & it works fine. It had an nVidia GeForce 8400GS in there, so I hooked the cable up to the MoBo... still no output. It says "No input signal" then after several seconds, "Going to sleep". After making sure that the input to the monitor was set to VGA, I figured that it must've been that the user had put in the video card some time before & it had gone bad.
Here's where it gets interesting... the user then told me that a friend with some computer knowledge had installed the video board after the video on the MoBo went out, hooked the cable up to the nVidia card and saw that there was no output & threw in the towel. Now, after going to the HP troubleshooting webpages for both the monitor & the PC, I found this little gem.
"Step 4: Reset and update the BIOS
You can use these steps even though you will not be able to see anything on the monitor.
In case an item was changed in the BIOS, such as the primary display device setting, use one of the following sections to reset the BIOS back to its default configuration:
Reset BIOS Version 7 or greater
Turn on the computer and repeatedly press the F10 key for eight seconds.
Press the Down arrow three times.
Press the Enter key two times.
Restart the computer.
Reset BIOS Version 6 or less
Turn on the computer and repeatedly press one of the following keyboard keys. Press the key about once every second for 5 seconds after turning the computer on.
For HP and Compaq computers that came with Windows 7 or Windows Vista, press F10 .
For HP and Compaq computers that came with Windows XP, press F1 .
For Compaq Presario desktop computers built prior to 2002, press F10 .
Wait another 5 seconds.
Press the F5 key. This restores the default settings of the BIOS.
Press the Enter key. This accepts the changes.
Press the F10 key. This saves the changes.
Press the Enter key. This saves the changes and exits from the BIOS.
The monitor should display the first screens received from the computer (the logo screens). If not, find and download the latest BIOS update if one is available for your computer.
If a BIOS update was not available or the monitor is still blank, continue to the next step."
Thing is, I don't want to reset the BIOS to the original default settings, but wish to change the BIOS "primary display device setting" to recognize the new video card, but how do I accomplished this in the dark? Any help would be greatly appreciated.
