Hello all, I have been stuck with this for some time, so I am hoping you can help me here. I've opened forum posts about this previously, but cannot link to them as I am new to this forum. Initially, I wanted to try the newer Catalyst drivers with Raptr so it could detect the drivers and allow auto config of game settings. Now I'm not so fussed with that however I have more annoying issues instead. Basically I bought this system around 2 months ago: ASUS Crosshair V Formula Z // 2101 AMD FX-9590 ~4.7GHz ASUS R9 290 DC2OC 4GB DDR5 Corsair AX1200i Corsair Vengance Pro RAM 16GB (CMY16GX3M2A2133C11) Corsair Carbide 400R Corsair 110i Water Cooler Samsung 850 Pro 256GB OCZ Vertex 3 120GB Sennheiser 363D with G4ME1 Generally it was relatively stable, I have updated the BIOS on motherboard and GPU to the latest versions, I was using the Catalyst driver from ASUS. I installed 14.4 and my system went to a black screen before install completed, I rebooted and tried again, it installed but on reboot and login I get a black screen. Similar but worse with 14.7. I then emailed ASUS who told me to RMA the card, they said it should work with the latest drivers. Ebuyer, the suppliers stated they ran the card in their test rig for 4 hours on 13.12 drivers, using Fur Mark, no problems. I asked them to try with 14.4 drivers, they stated they couldn't get them to install, they didn't give me any more information than that. They did tell me that this issue would be with the drivers, not the card and to report it to AMD, which I did, I'm still waiting for a response. I got the card back yesterday, did a fresh install of Windows, updated Windows fully, I decided to try the 14.8 drivers from this website, after a reboot, I login, then get a black screen, waited 2 minutes, but nothing appeared. So I rebooted in to safe mode and used the Driver remover tool found on this website to remove Catalyst, I then installed the 13.12 drivers instead. Also, AMD had recommended I use the following hot fixes for my CPU, I have installed both kb 2645594 and kb 2646060. After I had downloaded GRiD Autosport I tried a game, while loading the first proper race (after the training race), the game drops to desktop, the music was still playing in the background, but the game will not display anything. I rebooted and when I get in to Windows I leave my PC downloading games while looking in to the issue. While doing this Windows keeps locking up for a few seconds, you then see a bubble in the bottom right saying the drivr has crashed and Windows has recovered. So I removed the driver again. This morning I tried installing the "Chipset driver" from ASUS, which is just a catalyst installer, I tried running Fur Mark with that installed and it wanted a newer version of the driver installing, so I used the 13.12 driver from ASUS. I load Fur Mark after a reboot and run the 15 minute benchmark test, I went away and when I came back, the display had gone black, I had to ctrl-alt-del to get Task manager open and killed off the display. I tried it again after a reboot, and my GPU temp rose to around 80 degrees C, then the display went black. I tried one more time, and (I only tested for 5 minutes, but that is longer than it lasted previously) and it was fine, GPU temp going up to 84 before I closed the benchmark (it didn't crash this time). I will try testing this further tomorrow night. At the moment I feel stuck, I cannot get my system to run stably even with just the recommended driver, and the later drivers from AMD won't even allow me to get in to Windows. I have been told by the supplier that my card is fine, but when I test my system with the same software I get a lot of crashes. Can anyone advise whether there is any tool I can use to find out what is causing my system to be unstable? Looking on the ASUS website for my motherboard & GPU there are loads of applications recommended, most seems to be bloatware, and someone on the ROG forum said that he didn't use any of it, just installed the latest Catalyst driver, using the same motherboard, but I suspect not quite the same r9 290 from ASUS as I have. The one piece of software I _HAVE_ to install is the network driver, as without the one on the CD I cannot even get my system to connect to the network, beyond that I have tried with just the newer and other versions of Catalyst, but my system is still unstable. Can anyone recommend what drivers I need to use with my system? Sorry for such a long post, thanks for any help.
