All of a sudden my computer stopped detecting my Nvidia GTX 760 Ti OEM. I factory reset my PC and it seemed to work again however after updating Windows the problem returned. As an experiment I factory reset a second time, however this time it has not detected it at all. When accessing the device manager the Nvidia card does however show up under display adapters but as a hidden device with the message, "Currently, this hardware device is not connected to the computer. (Code 45)". I am using the iGPU for the time being and have tried...
1.) Physically disconnecting and reconnecting the card
2.) Uninstalling and reinstalling the drivers, however the driver installer cannot proceed as it does not detect any Nvidia cards in the system

UPDATE:

It now seems that this is a boot issue. The card works fine but the computer ignores it and boots with integrated. Maybe there is a BIOS setting that needs to bee changed?

Any suggestions, or comments from others who have had this issue would be greatly appreciated.

Alienware x51 R2
Intel(R) Core(TM) i7-4770 CPU 3.4Ghz
Windows 8 64-bit
16 GB RAM
Nvidia GeForce GTX 760 Ti OEM

What happens now is I will plug it into the Nvidia card port, and there will be no display, at which point i plug it into the integrated port correct. I have made sure the card is connected properly and have completed several factory resets over the past few months. I currently only can use the Nvidia card because it has successfully booted several times, and I have only put my computer to sleep and never off for several weeks as I have had great difficulty getting it to come back after a shutdown.

I would do the following:

1) Get the newest bios from Dell/Alienware and install it
2) Check the default video out is the PCI-E card (not integrated)
3) Reseat the card in the slot, make sure its firmly in (no dust etc).
4) Reconnect the power connector for the card (should be a 6pin cable from the PSU to the top/side of the card)

Ok, if still no luck there, then its entirely possible your graphics card is going faulty. Any way you can borrow another to see if it exhibits the same issues (or not) ?

MERGED QUESTION
Question from CombatRespawn : "Graphics Card Dead? Am I Experiencing Symptoms? Nvidia GeForce GTX 760 Ti OEM"





Ok well it goes without saying that the GTX 760 Ti card you have is an Oem.

Meaning it comes with a single blower type fan on it with a shroud that covers the card.

I don`t know if someone has told you this yet CombatRespawn.

But with Oem based card with a single fan of the paddle wheel type.
Where the fan of the card blows cold air along the card after a few years of use if the card has not been cleaned or the shroud removed.

Between the fan and the cooling solution that fits on the Gpu to keep it cool.
The front edge of it becomes clogged with a thick matting of dust.

You have to remove the black shroud of the graphics card where once removed you will see what I am talking about CombatRespawn.

Simply use a small clean paint brush with soft hairs on it and remove the matted layer of dust blocking the front end and fins of the cooling solution fitted to the Gpu of the card so the air flow from the blower fan of the card is restored.

Put the shroud back onto the GTX 760 Ti card you have once done.

And you will see the max temps of the gpu on the card lower from 70c at idle down to 45 to 50c and when gaming the max temp should be around 70c ect roughly.

Alright, so I installed and confirmed that I have my system/board's recommended BIOS version, BIOS default graphics is discrete, and as well, I disconnected the card removed it from its shroud and cleaned both the fan and the exhaust. Then I reconnected the card. I currently am using the card but I still have problems booting as it almost seems random as to when the PC boots with the integrated or the GTX. The main issue other than this are seemingly unnecessary crashes. I was playing Tropico 5 and MSI Afterburner reported a temperature of +90 C and ~95 GPU usage with all setings minimum on 720p (obsurd as a year ago I would play games like Arma 3 at best graphics at 50-60 frames). Thats just an example however, these crashes occur with dozens of games. I noticed very irratic behavior in the log at the moment of the crash.

http://imageshack.com/a/img921/9240/1oZru8.png (Note the Spikes in power usage; its very easy to see when the crash occurred)

Like I said, it almost seems so random, even after two factory resets, that it must be a hardware problem.

And sadly no, I am not aware of any other graphics cards I could test my suspicions on. My only point of reference is that almost all these problems seem to be graphics based, and when I have used the integrated, I have never experienced crashes. However, I have only used integrated on less intensive programs (due to lack of power) and I have only used it probably 20ish hours over the past few years.
