Thanks for the reply's. I managed to get it to operate by a fresh reinstall then loaded the drivers from my factory CD, that seemed to get optimus partly working. This allowed the computer to recognise the gtx680m in device manager so I could install the drivers for it. The card is operating alongside the hd4000 when I look in afterburner, but if I switch graphics with Fn F7 to the 680 only, I still get a black screen only. Current Bios is 80.04.33.00.32 now I can see it.

Hi guys first time posting here. I'm hoping for a little help. I have a m17xr4 quite a few years old now which has gone through a couple of GTX675m's now. So recently I purchased a GTX680m from ebay and after installing I am getting a blank screen, with no back lighting or signs of life.Fans/Lights run and I hear windows start fine, but I'm unable to switch to internal graphics after pressing the Fn F7. If I hit enter I hear an error menu so something pops a new window up. If i remove the GTX680m it displays fine with its internal hd4000 graphics. I have been speaking to the seller and found that the card is from the M17xr4 120hz wide FHD 3D. My model only has the 60hz screen but I didn't think this was a concern. With the card fitted the GTX680m warms up a little. I removed the Nvidia drivers before installation through the control panel and also DDU. I have tried Blind flashing the vbios with a stock bios sent from the original owner and also one from techpowerup with no change. I used nvflash v5.14.1 Dos version, I get 1 chime when I press 'y' 20 seconds in and get another chime 20 seconds later so I feel it has flashed but cant be 100% certain as I cant see. Any help is greatly appreciated. Many thanks. My specs: Win 7 home premium Processor i7-3720QM 2.6Ghz A12 BIOS stock 8GB Ram originally a GTX675m which recently died 17.3" wideFHD (1920x1080) WLED LCD non 3D
