GeForce 8400 GS detected, but not transmitting
My nVidia GeForce 8400 GS is seen by the device manager and seems to be working, but it doesn't seem to transmit video signal.
I just put a fresh installation of Windows 7 on my PC, I have the latest drivers, and the graphics card worked with Windows XP before I changed the OS. I am currently working off of the on-board graphics via VGA, but when I try to plug my monitor into the nVidia card with the DVI (same monitor, different source), the "Screen Resolution" window doesn't recognize the 2nd input. I also cannot get any signal from the card if I boot up with either cables plugged in.
I don't see anything in the device manager or in the HWiNFO32 program I have that throws any red flags. It appears to be working fine. And BIOS doesn't have any settings that should be interfering with the card working properly...
I'm pretty tech-savvy when it comes to computers, but I'm still learning Windows 7 (as opposed to my vast experience with XP). Am I missing something? Maybe the card went bad about the same time I installed Windows 7? Help would be greatly appreciated! :)
