so, been having this problem and been working on to get it fixed all day but did not, the problem is the gpu is not fully working what i mean is when you start windows it seems that you have never installed a driver, i tried to open nvidias control panel it shows an error msg says "you are not currently using a display attached to an nvidia gpu", so thats the main problem my gpu is not fully working...
What happened exactly:
was playing WoW trying new addons when suddenly my machine restarted without bluescreens or anything, then windows starts without detecting my gpu, restarting again and then baam the gpu's fan goes on 5k rpm speed.. i mean DAFUQ... a few restarting makes the gpu fan runs crazy fast.... restarting again and nothing...
my monitor working fine, vga/dvi cables are in good standing, temps are low 60max for cpu and the gpu can be detected from HWmonitor and having 40c, am using MSI Afterburner to control fan speed and doing a good work.
AMD Phenom II 955 x4 cpu
Gigabyte GA-MA78G-DS3H rev1.0 mobo
Gigabyte Superb 720W PSU
What i've tried so far:
-reinstalled fresh windows, been using win7 and now am on win8x64
-installed and reinstalled Beta drivers and WHQL drivers....
-clean dust in case and in the graphics card
Happened to me, I had to reinstall windows.. you can get it to read by deleting your driver in the device manager (make sure you delete all NVidia drivers) and restart computer. install driver manually in device manager. install the oldest copy (windows one.) then restart. try to reinstall driver from your hardware disk that came with it... it will read it, but for me I started having issues of it failing the install. then it just kept saying I could not start the install because I needed to restart my computer..
needless to say, I never got it fully working right..
It was because of the intall process windows uses, between windows and the antivirus.
I reinstalled windows 8 and my card was working perfectly..
I honestly think it is windows media center (when I installed it) then tried to update my driver from NVidia. that that was the reason my gtx670 was not reading right..
Hi, I have the identical problem with my second GTX 470(MSI N470GTX) in my SLI configuration. First card is Asus GTX470 and it work ok. I read a lot about this problem and no solved solution anywhere on the web. I think may be due to overheating PCB crack on solder cause this bug with driver issue and failure code 43 in Device Manager. Have you tried the roast in the oven because sometimes help?
