Spent 3 hours online to nvidia tech support one day, new driver wouldn't update, asked me all sort of questions, virus programs used, hardware, overclocks, web browser and download location etc
After failing to find the fix using his methods of trying to get it to not stall, he said something along the lines of "well I'm stumped, the only time we get this issue is users to have AVG but you don't"
Queue me raging at him saying I told you 3 hours ago I use AVG, upon checking he was very sorry and gave me a free game code. But just the pure hell of having to sit there going through things was hard.
Can't really blame him, he just missed the most vital piece of information during the start of the conversation. All was well and know I can just laugh about it.
