M9750 Dual 7950 GTX Tried to update Video Drivers.

Hi,
I'm running an M9750 R1 with dual 7950GTX video cards. I'm trying to update the drivers and try some different ones but I seem to have got myself into a pickle. I uninstalled the drivers from Device manager, rebooted, stopped Vista from installing its own drivers. Ran Driver sweeper to remove the display and chipset drivers (should I do the Physyx ones aswell?) Well I tried installing some other drivers but I don't seem to be able to get the Nvidia control panel back..Can anyone point me in the right direction for what I am doing wrong? I followed the SLI set up instruction thread but I must be missing something. I am just about to try an install the Graphics Driver 7.15.11.5655 which is what I had installed before to see if I can get the control panel back...Am I missing something..?
Any advice greatly appreciated.

 

Never had that problem when I still had the 7950's. You are uninstalling the drivers then rebooting into safe mode to run driver sweeper right?
Incidentally ensure you use laptopvideo2go drivers with the modded inf files. After you extract the driver package and replace the inf simply run setup.exe and it should install everything.
I would recommend you have a look at the m9750 SLI guide on this forum posted by Stone825

 

Thanks Simon..Well I eventually got it sorted so not sure what I was doing wrong...I downloaded the drivers from my hive support area but when I enable the SLI it reboots, lets me log on and then blue screens out...Is this a driver issue or is there a problem with on of my cards? Are there any diagnostics programs I can use to see if I have a card problem? They are both visible in control panel and in GPU-Z so I'm really quite stuck..

 

All i can suggest is pull the secondary (Parent) graphics card out and if it doesnt blue screen then either the card or the motherboard slot is faulty.

 

Plus the official Alienware drivers were/are allot more sensitive to enableing SLI. I really would either get the official drivers from nVidia (179.81 beta I think) or try some of the modded drivers from laptopvideo2go. Also, it is good to know what OS you are running.

 

Actually thinking about it, to install the laptopvideo2go drivers after cleaning out the system with driver sweeper i'm sure you had to cancel the install for the second card and then reboot and manually install the second card through device manager then reboot again and enable SLI.

 

Actually ever since the 185 driver series I never had to do the trick of canceling the second card install. It always did it automatically and the system just needed one reboot to get it working again. It may be just me though.

 

Thanks for the replies guys...and sorry I forgot to put I am running Vista Home Premium at the moment. I haven't installed any laptoptogo drivers yet..I was messing around with the Beta ones from my hive support page (179.13 beta) but for some reason the Nvidia control panel didn't install with these and everything seemed to be a bit juddery. So I uninstalled those and went back to the 7.15.11.5655 driver set also from my hive...They at least have returned me to where I was but then I tried to enable the SLI and it blue screens and I am out..
Is my best next step then fgoing to be trying those 179.81 beta drivers from nvidia to see if there is a prob with the vid card? Thanks for your help

 

Another quick question....I obviously notice quite a difference when playing some games without being able to enable the SLI...if one of the cards really is knackered then is there now a single card that fits which would give me similar performance to the 2 x 7950s? Thanks. I'm downloading the 179.48 drivers from nvidia now..
