I've bought a new pc with the following specs:
Sapphire Radeon HD7870 2048MB DDR5/256bit DVI/HDMI PCI-E
Intel Core i5-3350P 3,10 GHz
ASRock B75 Pro3-M
Crucial 2x4GB Ballistix sport 1333MHz DDR3 CL9 NON-ECC DIMM 1.5V
Seagate 1TB, SATAIII, 7200RPM, 64MB cache
Thermaltake Smart SE Modular 530W
I've installed windows 7 on it with no problems. It has detected my card as a standart vga cart. I've downloaded and installed latest cataclyst drivers and after rebooting the pc after the windows logo the screen went black.
When i removed the driver in safe mode the system in device manager recognised the card correctly as hd 7870.
Ive tried the following measures with no result:
-using both dvi and hdmi ports
-reinstalling windows 7
-installing different versions of catalyst drivers (both different old ones and new beta ones)
-installing the driver using device manager function and targetting the amd folder
-installing windows 8- in which case the black screen appeared during its installation during "getting devices ready" screen
-flashing my bios to the newest version
After inserting and installing my old gpu : msi geforce 460 gtx everything works fine.
So here comes my question:
Is it a hardware problem with my 7870 and should i return it to the seller or should i troubleshoot some more?
Thanks in advance!
PS:English is not my native language so I hope everything is understandable.
Unfortunately, I never had time to do it, and stuck to Win XP. Above all, I am very lazy.
Note that several months after, people states they have flashed the BIOS and now it works.
I hope this helps, and I add a question on my own: anyone has a SIMPLE, bullet-list style answer to help me flashing the BIOS? what file/program do I need? That post says to tinker with USB flashcards, etc...
NOTE: I've seen your answer luckiest charm, and I reckon it. But somewhere I have seen that there was an ad-hoc BIOS update just tailor-made to that specific card. Just my 2 cents.
