Hey guys. I'm having some PC issues. When i'm 5 mins into a very large MoW map, my PC insta-shuts down. This doesn't happen with any other game, or with a standard MoW map. Just larger MoW maps (mods). It didn't used to do this. Anyway, I assume it's an overheat issue. So I did some de-dusting and bought an extra 120mm fan and arranged for it to blow cold air into the system. The issue persists however. About 5 mins into this MoW game, and i get a hard shut-down.

I've attached some temperature readings.

Any clues boys and girls?

Those temperatures are nothing... they're actually pretty good. Were those taken prior to MoW killing your computer? Yea, nm, guess so, from your graph. 60C really isn't bad. In fact, it's really cool for most GPUs. Shiny's runs around 80C I think, and that's normal for her GTX465. My gtx670 runs around 60C as well normally in games.

Now, I suspect what's happening is your machine is blue screening and auto-restarting. Check c:\windows\minidump and see if you have any dump files coinciding with the date/time of your crashes. If you do, try posting one... I can debug it and tell you what's causing the BSOD.

Ended up being a lack of power from the PSU. Got a new 650W one. Fixed.
