Hello Shinzetsu!

We launch an article related to that issue a couple of days ago, check it out and let us know if it helps you to fix the problem. 

I did all the solutions but it didn't work. Still my laptop can't detect my graphics card it says you are not currently connected to your nvidia gpu in the device manager there is an exclamation symbol on my gtx 770m. But i notice something when i disabled and enabled my nvidia it worked what could be the problem?

Depending if your card is bad or not if you do this it may fix the problem. Open the bottom panel and remove the battery, then remove the GPU (Nvidia) you do not need to remove the heatsinc just remove the fan and the GPU with heatsinc attached and then reinstall it. Most of the time if the card is not bad it fixes the problem.

will it void my warranty? if i opened my laptop? if my graphics card is faulty i cant access it right? something is disabling my nvidia please help :( ive been reading many solutions, visiting forums but still i cant fix this :(

The cards are super easy to access on these new Alienware 17 and 18. When you remove the bottom panel its the large card top left. Two screws hold it in place lift up and out done. There are tons of videos showing how to do this. This should not void your warranty. I would call Dell support have them walk you thru the steps if you are really unsure. Mine went dead on me called support we walked thru all there steps (Even though I am a 20yr Tech) I did it with them came to the conclusion its a bad card. They sent me a complete replacement kit and I replaced it my self no issues still covered under warranty.

I have GPU problems on my Alienware 17, my graphics card cant be detected i have tried solutions in this forums,searching google and visiting other forums but it didnt solve my problem however im waiting for the reply of the moderators here at Dell Forums. I still have the RECOVERY partition because i formatted my laptop how can i restore my laptop in factory image? because i cant see the alien restore at system repair :( can i do it manually because i have the Factory.wim. Hoping that restoring my laptop to it factory setting would fix this problem. Please help me :(

I wnt to open it right now but im scared i might break it im not good at fixing those things. When i hibernate my alienware it is ok the nvidia is detected it works fine but when i use shutdown nvidia wont appear i have to disable and enable it in the device manager after a couple of enabling and disabling it nvidia will appear. It may be loose right?

The Alienware 14 is the only one that has the Nvidia built in the board. The 17 and 18 both have removable graphics cards.

Wish i could call dell but im here in the Philippines. Is the graphics card removable? It is not soldered or something?

Are you using the drivers from support.dell.com?
