So I recently purchased the Sapphire HD 7870 XT with boost card from Newegg.com to use for gaming purposes. I installed it, worked prefectly for a couple weeks and now I'm running into an issue with it. First off my machines specs are:
MoBo: Gigabyte MA785GMT-UD2H
CPU: AMD Athlon II X4 630 2.8 GHz Quad Core
RAM: 2x OCZ 4GB PC10666 DDR3 1333MHz
PSU: BFR GS-650 650 watt
OS: Windows 7 64-Bit
My mother board only has PCIe 2.0 and the card is 3.0 but I was told that it was backwards compatible and would work. So I bought the card and it worked great, was getting an average of 46 fps on the highest settings on WoW. Yesterday I was gaming and everything was running smooth until my screen blanked and gave me No Input then my desktop came up. The game was still running and my mouse cursor was still the hand from the game and I couldn't click anything until I Alt+tabbed to my desktop. I opened the task manager and closed the game then ran it again, put in my password, selected my character and hit enter world. The game fully loaded and then blank screen and desktop again, same thing. I tried running Bioshock and Tomb Raider as well and the same thing happened, I opened steam, started the game, it loaded and then desktop. So I uninstalled the drivers with the amd uninstall tool and went to the website and installed the latest driver again. Ran the game, same thing. I pulled the card out, dust offed everything, made sure the card was making a good connection and tried again. Still giving me the same problem. I removed the card, removed the drivers, plugged to my onboard graphics and installed the drivers and the game ran. Today I tried the card again, installed it, dowloaded the latest driver and ran the game. Now the game starts, I take 2 steps and the screen freezes for 10 seconds then does the same thing sending me to the desktop.
I can still use my computer with the card installed. I can do any normal functions and Youtube videos play in full HD/full screen. Just whenever I play any games it gives me that error.
So my question is am I just screwed and the 3.0 card will not work with my 2.0 pcie board or is there any other solution? I'm just stumped because the card was running great up until now. If I just buy a new mobo with pcie 3.0 can I salvage all my other components (specifically the cpu) and make it work? I hope somebody can help. And if you made it this far, thank you.
