How to diagnose random freezes (prob hardware based)?

History

I've got a mid-2010 Mac Mini which had been flawless up until a week or two ago. Now, roughly once a day, I'm getting total random freezes. When the freezes happen, sometimes everything just stops (mouse won't move). Sometimes video goes berserk (horizontal lines of different colors). For this reason, I'm suspecting some kind of hardware failure.

Are there any guides to help me troubleshoot/diagnose the specific part that could be the problem?

Start up from your original system installation DVD and hold down the "D" key while starting. This is the AHT (Apple Hardware Test). Let us know your results.

Thanks mayer. Did that, and AHT says no problems. (Phew!)

David Das,

If it's not a hardware problem then...... Run Disk Utilities from your system DVD.

mayer,
