Cant enter my Nvidia control panel !

I cant enter my graphics card control panel and when i went to Nvidias site and tried automaticly detect my GPU it said i have no Nvidia GPU. I do have NVIDIA GeForce GT740M and it worked very well for the first day i bought this computer. Now i cant get to my Nvidia control panel.. When i try to get in there it says that my monitor is not connected with Nvidia graphics card. When i try to play Battlefield 3 it plays with my integrated Intel HD Graphics 4000. How can i get my GT740M working again ? I refreshed my computer without loosing any apps from my windows 8. Lost only my deskopt programs. It didnt help. I tried to upgrade to the latest drivers but it didnt work. I deleted the latest drivers and tried to install a bit older drivers but i couldnt do that (Dont remember what it said). My Nvidia Geforce Experience didnt recognise my GT740M either. Is my graphics driver broken or is there some decently easy way to reconnect it. I dont see any reason how it could have broken in my use. My Nvidia also disappeared from my system tray.

I really appeciate helpful comments.

Thanks.

Well, it seems like an hardware issue as it happened to me recently , in that case u should visit a near-by repair shop or call the customer support of the graphics company. (If warranty still applies, your lucky)

I ran System Requirements Lab program and detected my system.

Windows Version: Microsoft Windows 8 (build 9200), 64-bit
Processor: Intel(R) Core(TM) i5-3230M CPU @ 2.60GHz
Graphics Card: GeForce GT 740M
Total RAM: 7.9 GB
It still detects my GT 740M...
Can it be broken if that program still recognises it ? Cant it be that it just have disconnected or turned off and can be reconnected or turned back on ?

i did update my windows 8.1 yesterday evening and after that i have had 3 failures and had to reboot. Cant remember what the first failure were but 2nd was DCP_WATCHDOG_VIOLATION and 3rd one were VIDEO_TDR_FAILURE and that happened 2 or 3 times. Then my Nvidia didnt work anymore, only my integrated Intel worked. I did upgrade the latest graphic drivers with GeForce Experience but then then error (VIDEO_TDR_FAILURE) happened and i went to nvidias site to search newer drivers manually and found them. Installed them (I did delete older drivers before doing that) and could play for a while but then the error happened again. After that i manually rebooted my computer but my nvidia didnt show up. I went to my control panel -> Hardware and Sound -> Nvidia Control panel but it said that cant acces the setting becouse im not using a display that is connected with Nvidia GPU.

I did total reboot for my computer and set it back to back to the settings as it was when i got this and my Graphics card were still working but it still says this when i go to device manager "Windows has stopped this device because it has reported problems. (Code 43)"

So is it broken ? Do i really have to send this back and have wait for for a ******* month to get it back... ? Im so sick of this new technology, everything gets broken when even have a eye on it.. Sorry for this little rage, im just so frustrated after 10+ hours of research for this problem.

Is there any way to fix this without sending this back to store so they can have a look at it ? I really dont feel like waiting it back, it usually takes so long.

Any ideas what could have caused this ?

Going back that far only means that Windows has been taken back (System Restore effects mainly Windows own system files) and now probably severely needs updating. Make sure that the card is seated properly and then go into the BIOS or whatever software may be installed for that purpose and remove any over-clocking.

Uninstall any Nvidia software you have, as I suggested earlier. Warning your screen will go low-resolution until you reinstall new drivers.
