It happened without fail, since my home-office PC sleeps and also supports Wake On Lan so that I can wake it up from work using Logmein. It went from being 100% reliable (no crash since being built) to locking up every single day whilst I was at work.
I obviously tried all the usual diagnostics; MemTested, Furmarked, Crystal Diskmarked and Prime95'ed it but it wasn't a stability issue. Remembering I was on the betas, I rolled back to the 12.10 WHQL version of the catalysts and the problem was fixed.
I wonder if the issue they had with those betas has snuck into the driver you're using for your Trinity. Assuming you're running release drivers, uninstall them and revert to the "Standard VGA Adapter" before setting your sleep to 10 minutes to see if it happens again.
