GPU Not Recognized

Question

I recently bought a Radeon HD7570 for my Inspiron 660s, but after installing it it isn't being recognized by Windows in the device manager. I have an information/stats program called WhatPulse that is detecting it and showing it as AMD Radeon HD7570, but Device Manager shows it as Standard VGA Graphics Adapter.

I have tried to update the drivers but AMD's driver installing software can't find the GPU either. Attempting to manually install them didn't seem to work either. The card appears to be powered, as the fan is on.

Is there anything I could try to get Windows to recognize and use it, or could it be related to the PSU just not being powerful enough for the card? I am running 64bit Windows 7.

Cheers, SearedFox.

7570 adapters are OEM and not recognized by the Generic Drivers.

Uninstall any existing video drivers from the machine first.

If this is a Dell Video card Download and install the drivers from the support site (http://dell.to/ROiEZt)

Downloaded and installed the drivers (Catalyst Control Centre just said that all componenets were up to date, so installation might not have happened), then restarted. No change. Pretty sure the only graphics drivers left on the system are for the integrated Intel HD Graphics. Do those need to be uninstalled as well?

Is there any way I can force device manager to manually install drivers? I tried by clicking "update driver" and selecting the unzipped (and apparently installed) Dell drivers, but no luck.

I don't have a Inspiron 660 so can't be specific for this system...

One thing to note is that some systems will automatically disable the integrated video function when a PCIe based video function is detected during the boot process (a card PCIe video card has been installed) and allocated the needed resources. Other systems may need the owner to explicitly change the BIOS settings and disable the integrated video function so that the PCIe video function can be detected and allocate the needed resources. Yet other systems require the owner to set the BIOS to 'integrated' or 'PCIe' or 'auto' depending on their needs. It's all very much dependant on the system BIOS and how it was coded... But BIOS needs to do its magic so the OS can see the hardware correctly...

So have a look within your BIOS for "integrated video" or words to that effect and change the seetings for this item to 'PCIe', 'auto' or 'disable' depending on what is available on your I-660... Then hopefully the OS will see the hardware corretly and you will be able to install the drivers without issue...

Hi,

Download SPECCY and click file > publish snapshot > give us the link so we can see all your specs. I'm assuming you are on the absolute latest version of your BIOS and your windows version is fully updated?

Here you go: http://speccy.piriform.com/results/sGZMT18tnFPi1liVVkS5TkJ And yes, I flashed the bios before installing the card and Windows is updated I believe.
