Indigo 0.6 restarts my PC :(

[motorsep]

Don't remember such thing happening with Indigo 0.5, but with 0.6 after about 15-20 min of rendering, my PC restarts/shuts down.
Any ideas why?

Heat issue I bet... Try to install a heat monitor like ASUS PC Probe II direct link (if you own an Asus board. Every manufacturer has similar tools). If that's the issue try to see if your comp works best when its pane is open; it's not recommended but works for me (can lead to higher temp, depends on how it's designed. Mine goes cooler when it is open).

Overheat cpu, time to vacuum;)
