When it happens, go to device manager and disable and enable the gfx card. This will quickly restore functionality to the card, but whatever program you were running on it will have crashed (or at least show a perpetual blank screen) and you will have to open them again. If you are running GPU overclocking software such as MSI Afterburner, you will have to tell it to re-apply your overclocking profile again.

 

Tech Inferno Fan says that since the EXP GDC uses a socketted connection between the adapter and the laptop, there may be signalling issues which cause intermittent dropouts. Your best bet is to secure every connection as thoroughly as possible. Find some way to put constant downward force on the adapter side of the cable.

 

I did this and I rarely get these random dropouts any more.

  
nice tip with the device manager, ill try pressuring the connectors when i have the chance but im still not sure how everything should be connected there, the PSU have a lot of cables, im also not running any overclocking software because this gpu is already factory overclocked  

i just remembered that running some games on an external monitor the gpu stop physically working so there must be something missing

i've also read that installing the Mobile version of the GPU driver helps, lastly can you share your setup?
thanks a lot for your quick response 

hey guys I've recently bough the EXP GDC V:8.0 (Mini PCI-E) for my Laptop HP Envy 15-j052nr 
it works fine most of the time but... this is my setup:
EVGA GTX660 Superclocked, Drivers installed from the GEforce support page for the same model
PSU EVGA 500W 80PLUS certified
Laptop Specs:
8GB DDR3L RAM
Intel HD Graphics 4600 with 1792MB total graphic memory
2.4 GHz 4th generation Intel Core i7-4700MQ Processor with Turbo Boost up to 3.4GHz
Windows 8.1 X64 

my issue is that while connected to an external monitor all works fine but working with the integrated display most of the time the GPU suddenly stop working, shutting down the pc and turning it back on is the only way to fix it whenever it happens, I've been reading this thread quiet a bit and I've seen people struggling with drivers and insufficient wastage and i just want to make sure my setup is ok. Thanks in advance
