Seemingly random hangs...

[Zoidoid]

So I built a new Sandy Bridge rig about a week and a half ago. So far it's been brilliant (aside from not being able to get my Samsung HDD to be detected on the Intel SATA controller). However, four or five times the computer has hung. And in most cases if I'm very patient it eventually recovers. During the crash I can move my mouse but windows is COMPLETELY unresponsive. I cannot even bring up task manager. What are some potential causes for this behavior? It doesn't seem to be stress-related because I've played game for hours without a problem. I've also been able to do some heavy HD work in After Effects (and render files out) without much of a hitch (though once this did trigger the freeze!).

I'm leaning toward the problem being the Samsung drive or the Marvell controller. Could HDD issues be responsible? Note that I have Windows 7 installed on a separate SSD. Here's the rig:

- Intel i5-2500k
- Asus P8P67
- Crucial RealSSD C300 120GB (with Windows 7 x64 installed) and plugged into the Intel controller (6 Gb/s).
- Samsung HD103SJ 1TB for storage (and some programs) and plugged into the Marvell controller (6 Gb/s).
- G.Skill Ripjaws X Series (2x4GB) currently running at 1300 it seems (should I manually set this to 1600)
- Antec EarthWatts EA-500D 500W power supply
- ATI HD4770

Any advice would be appreciated!

I had a similar problem and for whatever reason it turned out to be bonjour was the culprit. I figured that out through the error logs. If you have iTunes installed, go into services and change bonjour's start from auto to manual. If you don't use iTunes too transfer music to an iPod you can remove bonjour altogether.

that RAM running underclocked doesn't help things - set it to 1600
