Question: I installed this card, inserted cd, but still no video.  My computer is asus cm6730-04.Can anyone help with my problem? The monitor is good. Bad motherboard perhaps?
Document: Item was as described, installed into old windows xp computer. However, installation software did not allow for multiple monitors. Not a fatal flaw since I have one large screen monitor. Performance improvement was noticeable but not dramatic.
I installed this card in my desktop machine, built as a near-silent media PC. It worked fine for 30 days, and on the 31st day, one day outside the Amazon.com return window, it had a complete failure; the display is completely corrupted and it is clearly a hardware failure (trust me, no software way around this one, I've tried all the possible solutions).Now I'm stuck with a broken video card, no working desktop computer, and outside Amazon's return window. Awesome.
Installed the EVGA GeForce 8400 GS on a ASUS M3A78 Motherboard. Setup was very easy. Allows for some video editing.
We purchase 2 Dell desktop computers with what they indicated was dual monitor capabilities but VGA monitors wouldn't work so I purchased 2 EVGA video cards for them and they installed according to directions and are working great. I have used similair cards from EVGA before. Will purchase again if I am in a similair situation.
I was re-purposing a PC to be a server and wanted a no-thrills video card, and the 8400 was what I came up with. I mainly wanted card without a fan because in a server that's on 24x7, video card fans tend to crap out eventually.. and I didn't want that headache later on. I can't speak to its gaming ability, but it runs Windows Server 2013 Essentials without a problem.
Installed the 1st time and drivers loaded without a hitch, came up with both monitors working and It works very well! Would buy it again for another PC if I needed another dual monitor card.
This card replaced the onboard graphics adapter and provided us with a dual monitor setup. Great resolution and speed. Installed without a glitch on Windows 7. Great quality and performance particularly at this low price level. Everything was exactly as I needed with great delivery time as well.
First you have to go to the BIOS settings to select the PCIe as your video card destination and disable the existing video card before you install the drivers for a new video card or the new video card.Good luck.
So far it has a great picture and plays good movies etc. My issue was I had a HDMI monitor with no Ge Force HDMI connection. I ordered this and hooked the HDMI up. It found all drivers plug and play and then rebooted. It works great.
The best upgrade my system received is the EVGA GeForce 8400 GS Graphics Card upgrade.MY System Specs:Compaq Presario SR5214X Desktop, Windows 7 32 bit, Intel Core 2Duo 1.66GHz, 2GB DDR2 RAM with onboard shared memory Intel GMA memory card.My requirements:I wanted a simple video card with a HDMI slot and enough memory to hook it up to a HDTV monitor.
Answer: it can be anything from the motherboard having a wrong setting to a driver issue or a video conflict. you should call an it pro. if you are in the tampa, fl area or can at least get on it and go to the internet then tampacd.com they can remote in and fix it if you have internet.
