I recently put together a system with 2x asus gtx680-dc2o-2gd5and it's been running fine for about week and a half. Last night my system crashed after playing starcraft 2 for about an hour. Now steam doesn't recognize my gpus at all. Batman Arkham City doesn't work, Anno 2070 starts but crashes my system, skyrim works, and I haven't tested sc2 yet. I've tried reinstalling directx 9 again as well as reinstalling nvidia's newest drivers.
What do I do? Device manager doesn't report any issues, nvidia control panel says everything is working properly. My Batman copy isn't part of steam and I've had significantly longer gaming sessions. Could one of my graphics cards be bad and how do I check? If I install steam will I have to reforms all my games? Because I have over 100GB in steam games.
i've already attempted that, doesn't do anything, says i have a newer version of directx already and that it won't install.
i've also tested out both video cards independently without errors...i'm thinking i should do a clean install of the operating system because from what i've read it says that rolling back to a restore point will not resolve the directx issue.
You can always run "dxdiag" to test your directx components.
Under the Windows start button, find "Run..." and type in "dxdiag" without the quotes.
I recommend you do another install of the 301.42 WHQL drivers by completely uninstalling the current drivers through the Windows Control Panel add/remove programs dialog, restarting the PC, then selecting the "Clean Install" option when installing the new drivers.
For Steam games, you can "Verify the game files". In your Steam games Library, right click on the game you are having problems with, select "Properties", select "Local Files", select "Verify integrity of game files..."
do you think it's the board? is there a program i can run to test it? should i downgrade my bios?
Hard to say, but I went through something where I RMA'ed a power supply and video card and did all sorts of things before I finally figured out it was a defective motherboard. Then, they RMA'ed my motherboard with another defective one!!! Talk about aggravating, but I finally bought yet another motherboard and everything was fine.
that blows, last thing i want to rma is the board, so much work involved getting it out and putting another back in... i think i'm going to try to call asus tomorrow and see if they could help me out in terms of resolving this issue i guess, since i primarily did buy asus products.
at first I thought it was the pcie x1 sound card that I had that was crippling it so i took it out, when i restarted the problem was still there, then i reinstalled the lastest bios (1015 for the second time) and it went to pcie 3.0 x16 @ x8 1.1, nvidia control panel says its pcie 3.0 x8 on each of the profiles for the gtx's, then i put the sound card back in and no bandwidth problems. steam still doesn't know what video device i have. i'm going to try to reinstall nvidia drivers and see what happens.
I don't have access to another mother board that supports pcie, three computer I replaced was still using agp graphics slots, but I've already determined the crashes happen even without the video cards.
so i replaced the motherboard, but now i'm getting terrible fps, i used to be able to run batman arkham city on full settings with 8x MSAA and get an average of 60 fps but now it won't even run the benchmark at those settings, looking at the ASUS gpu tweak software one of my gtx680s isn't fully starting up, its only half ass running, i think i might need to replace it.
