Once two days ago. Twice yesterday. Three times so far today. Has to be physically unplugged for a few seconds before it will turn back on. Does it while idle or while in use. Always the same symptoms: the image is still on the screen but no response to any inputs, and nothing shows up in the logs. The last time it froze while writing a Photoshop file and corrupted that beyond recovery.
Help, please? This is getting frustrating.
