...at least partial good news though re the 1st 'cycle...I don't consider myself an expert on sleep modes, but you don't seem to be dealing with a hardware failure if I understand your descriptions correctly. Further, don't really know much about 'parted magic' but when I typed it in Google w/sleep mode, I got a lot of hits like 'my computer fails to wake up from sleep mode wi/parted magic' i.e this: http://forums.partedmagic.com/viewtopic.php?t=2197
...so what I would do right now is to take 'parted magic' out of the equation, just for now, if you can...if you still have problems after that, go into the BIOS / CPU Power Management and turn off all power-saving features (C states, Intel SpeedStep etc). The same holds for your Win 7 power saving settings.
You base point should be a perfectly running (not asleep) system you can test out with your programs to see if everything hums along. Then, I would start re-activating one power management feature after another, until he problem re-appears - but first, I would see what the parted magic forum on sleep modes say...
