I have gotten a few random blue screens in the last few weeks, not replicable, usally during playback.
What is the first thing to look for? Drives?
The machine blue screens and restarts everything is fine. Can continue watching the same video no issue.
I thought heat might be it, but it is cooler now than all summer.
Your source for everything home theater & HTPC related

Check your temps anyways.. overtime dust can collect...
In my experience heat, bad ram and bad psu are the major culprits.
What OS? What HTPC software?
