I've been getting this problem lately, which is extremely frustrating, as I can't work out what's causing it. Over the last few months, I'd occasionally experience a freeze, and the occasional BSOD. The error always said stop error 0x0000116. It didn't bother me that much, as it wasn't very frequent, untill yesterday. I fired up sketchup, and after 5 minutes, a BSOD. From then on, I couldn't boot into vista at all, every time it was just about to load up to the log in screen, another BSOD, with the same error code. I've re-installed vista 3 times over the last day, where it seemed to go nicely, but then after installing the ATi drivers, and then some windows updates, it'd go back into the circle of BSOD, restart, BSOD. I've been looking all over the internet for any similar problems, and I've came accross people who have had the same issue, but there wasn't any results of it. Anyway, I was begining to think this is either a windows update problem (ie, something like installing an update is the cause of this), or it's my 3870X2 that is failing. I tried an old 1600XT I had laying around to see if it was vista or the X2, and the 1600 worked fine, so I threw the X2 back in, and no BSODs on boot up, though my PC has crashed a few times, but no BSOD, so I'm now thinking it's not my X2 that's slowly dying, but it's something to do with drivers. It's extremely frustrating trying to figure out this problem. I've noticed a few other people on here seemed to be having a similar issue too, which seems not limited to ATi, but seems to be occuring with vista x64. Anyone got some input into this situation?
