Hi,
Thankyou for your reply. I did what you said but i am not able to update drivers when downloaded version 15.33.8.64.3345 zip file and unzipped in a folder and opened device manager then browsed through the folders and selected unzipped folder and clicked Next, then it says"Windows have determined that driver software for your device is uptodate"
But when i verified still it has old version 10.18.10.3308
Regards
