[SOLVED]
I bought this new GPU, the SAPPHIRE HD 7870 GHz Edition 2GB GDDR5. First, I unplugged my old GPU, a ASUS HD 5570 (which wasn't mine, I borrowed it from a friend), then I plugged the 7870 in, booted up, everything fine, I open up the driver setup I downloaded from sapphiretech.com, still fine, installation takes hours, but ok, finally done. Then I check the log of the installation because it says there have been some warnings, and at the end it says 'no driver installed'.
When I go to device manager, it says i'm using the 'standard vga graphics adapter'. The weird part is that my mobo (ASUS M5A99FX pro R2.0) does not have integrated graphics. So I checked GPU-Z to check whether it recognizes my GPU, and the weird thing is that it does, but only partialy. It says it's name is 'Standaard-VGA grafische adapter' (dutch), but the GPU-chip is recognized as Pitcairn, and the shaders (1280), Memory type and size (2048 MB GDDR 5), Bus Width (256 Bit), and default clocks (GPU: 1000MHz, Memory: 1200 MHz) are all correct. at Sensors, it says the following:
GPU Core Clock: 0.0 MHz
GPU Memory Clock: 0.0 MHz
GPU Temperature: 0.0°C
Fan Speed (%): --%
Fan Speed (RPM): --RPM
VDDC: 0.919 V
VDDC Current: 6.1 A
VDDC Power: 5.5 W
there seems to be something wrong with either my GPU or my mobo.
I tried plugging it in another PCI-e x16 slot, but without succes. Windows does see a 'PCI device', but does not recognize it as GPU.
I tried setting PEG/PCI to PCI/PEG in the BIOS, but without effect (I've switched it back later)
I tried removing al display drivers using a Driver Sweeper, and then reïnstalling everything, but without any difference.
Since I'm quite sure the GPU is working (I bought it second-hand, yes maybe stupid, but I checked at his place whether it was working, and he could show me it was), I'm affraid my mobo is broken. I can try to RMA my mobo, if nothing else works...
solution: I tried installing the vista drivers, and it went well. after that I could install the latest windows 7 drivers as an update.
