GTX 680M and M6600 issue. Black screen after installation

Good day,

recently i have replaced motherboard on DELL M6600 (gtx 680m installed) and cant install drivers anymore. Before Motherboard failure everything was OK, except there was a real hassle finding proper modded driver for my "custom" laptop, but i have found several revisions on LV2GO and installation was successfull.

But now, when i'm trying to install them - i get black empty screen after restarting the system (but all indicators and keyboard lights are on, so the system is running) or, on some of 30x.xx drivers i get 640x480 resolution without any chance of changin it and the color theme is 8 bit.

When i boot in safe mode, i can see NVIDIA GTX 680M on my device manager and when i'm trying to automatically update it, the device changes to "standard VGA adapter" and system begin to work after restart. Nevertheless, in "dxdiag" command i can see that the chipset name is GTX 680M with 4GB of VRAM, but the name of device is still Standard VGA adapter and my WEI is 1.0. Please help me

 

oh crap... after bad experiment with 780m was thinking about 680m=(

do you tryed bios resset? is your windows clean install?

btw is your bios version same as old one?

 

Will try reset, thanks, but dont think that will help, because i have my GTX 680M working perfectly before my motherboard failed due to punch with my fist

 

what is your card clevo/dell?
i assume clevo...

 

yeap, its clevo

 

I was unable to get a 680m stable in M6600. It was the first weapon of choice but after several tried, i gave up. It wasn't stable no matter what I tried.

 

I have updated it yesterday at a14

 

What happens if you don't install any Nvidia drivers? Does it work OK?

 

so any news?(

 

Hi guys, sorry for a dealy. Yes without Nvidia drivers everything is good, except i cannot work in any CAD software
