So I am trying to update my driver I have the NVIDIA GeForce 9800M GT in my alienware laptop. I go to the website and let it scan my computer and find the latest update and then download and install it. I restart my computer and when it reboots it runs fine for about 2 minutes and then it just freaks out! it goes black and then flickers and then changes resolution and then just goes insane until I force a shutdown. So I rolled the driver back but I was wondering if anyone knows what went wrong and how I can update my driver the right way next time. Any help would be appreciated
