Have tried to find answers on a few other forums, but figured it was time to come to the source.
I've got a Win8x64 HTPC (Core i5-2500k, ASRock Z67 Ext 4 Z Gen 3 MB, 8 GB RAM, ATI 6850 on Cat 13.1 drivers, OCZ Agility 3 SSD, WD Green drives) that's suddenly started producing the wonderfully corrupted image seen in the attached photo after a few hours of it not running through my processor (Marantz AV8801) to my TV (Samsung D8000 plasma).
A reboot resolves the image corruption immediately, and I'm yet to actually witness it happen (it's only ever become apparent after switching on processor/tv). Doesn't always happen either, but it's now happened 4 times in the past 5 days.
I've tried lots of googling around HDMI image corruption, etc. but can't seem to find anything that looks similar, or anything that's pointing me in the direction of a possible cause/solution.
I'm sort of suspecting the hardware here. Either the video card, the hdmi cable or even the processor (but have looked through the AV8801 owner's thread and didn't notice anything similar).
Anyone seen something like this? I'm going to try a new HDMI cable tonight, but if that doesn't fix it, I'm going out to purchase a new GPU. Hope someone's got a better (ie. no $$$) solution.
Thanks for your time in looking and/or helping!
