I have a Dell Vostro 460
Intel i7-2600
8g RAM
Intel integrated GPU
16x 2.0 PCI-E
Thermaltek 650w PSU

After installing my new AMD Radeon R7 260X, there is no video. I run my machine with mixed onboard and PCI-E graphics for Quad monitor support. BOTH the PCI-E and onboard GPU fail to give a video signal, if I unplug the 260x My on-board video works but the PCI-E card is not detected (obviously). I have tried booting in safe mode to no avail. Interesting thing is my keyboard num lock light won't come on during boot, meaning the computer isn't getting into POST operations. Can anyone help me out? I checked with Dell and this card is supported but they told me to take it back to Best Buy, which I did and the new one has the same issue.

Instructions for manually disabling secure boot:

1) Power down the system

2) Remove the Graphics Card

3) Boot the system using integrated graphics

4) Enter CMOS settings. CMOS settings can usually be accessed during boot, typically by pressing one of F1, F2, F8, F12, or Delete (depends on the system firmware) (if you have windows 8 let me know i can give you another method to do this)

5) Set Secure Boot to disabled

6) If there is an option, set CSM (or compatibility or legacy mode) to enabled.

7) Save the new settings

8) Power down the system

9) Install the Graphics Card

10) The system should now boot

I am running Windows 7 Ultimate

The BIOS version I am using does not have these options. HP uses the Secure boot but Dell does not, I have looked for it and verified it is not an option. I have also updated the BIOS to the newest version. The only option for graphics is Intel multiple monitor feature which allows me to "auto" select on board, PCI-E or both. I have it enabled which should allow mixed video however the on board GPU will not send a signal if the card is plugged in. It is also only an option if BOTH a PCI-E card is detected and cables are plugged into both ports. I could not find a legacy mode setting either.

Ok, Try This, Take out your new graphics card.

Turn your computer on and log on using Safe Mode. You can do this by pressing F8 repeatedly during boot up. You should come to a list of options; highlight Safe Mode using the up and down buttons, and press 'Enter' to select.

Right click on My Computer and select Properties.

Select the Hardware tab, and click on Device Manager.

Click on the '+' by the picture of a monitor. It should pull up your graphics device (something like Intel Integrated Graphics).

Right click on the device for your on-board graphics.Disable it, don't uninstall it; otherwise, this will cause you a world of trouble.

Log off, and power your computer off.

Remove the case cover and insert the new card in an empty slot.

Plug your monitor cable into the new card, and when you log on, it should run on low resolution until the driver is installed. It should find the new hardware, and from here, follow the graphics card installation manual. Sometimes it has programs that install the driver and not the Found New Hardware Wizard.

Hope this helps.

I did try that, the only option is to "disable" the auto feature which then selects one or the other. I have to re-install my old card to even get the option to come up, otherwise it is missing from the CMOS settings menu. There doesn't seem to be a way to set one or the other manually.

After combing the internet I think I found someone with the same issue, it was never resolved. They switched from the AMD card they were trying to an NVIDIA, I will be calling AMD tomorrow to see what they have to say. Appreciate the help, will let you know how it all ends up.

There could be numerous reasons for your problem with your graphics card.

Let me know what AMD say about it and hope you get it sorted soon.

After speaking with AMD they told me to take my computer into a shop and have it looked at.... Even after I informed them I am an IT professional and work for a software development company. Seriously disappointed in their customer service. I have a buddy who is willing to let me try his Nvidia 660Ti, we will see if that works. I spoke with Dell again just to get a list of compatible cards, all they sent me was a list of recommended cards to buy from them. I appreciate the help!! Hopefully I won't have issues with another card.
