Computer won't sleep after file transfers???

I've still yet to figure this out. After using torrent storm, the only program that seems to cause this to happen, I try to put the thing to sleep...and it hangs. Everything shuts down, but the computer conitunes to run, and is locked up. The only way to shut it off is to hold the power button. It's not making it to sleep mode, 'cause it won't ever recover by pressing a keyboard key, power button, etc. And now, I'm starting to get BSODs randomly in the middle of nowhere. Here's what Windows says after recovery. It's the minidump thing that I THOUGHT Microsoft fixed.

Problem signature:
Problem Event Name: BlueScreen
OS Version: 6.0.6000.2.0.0.768.3
Locale ID: 1033

I'm not sure if the BSODs and the no sleeping are related. If i don't use Torrent Storm, it has no issues going to sleep and waking up, but i still get the BSODs anyway, three so far in one week.

My system specs:
e6750 (stock), MSI P35 Platinum MB, 4x1GB Crucial Ballistix 800, WD 320 GB HDD, PC P&C 610 PSU, Antec Nine Hundred case, Vista Home Premium 64-bit.

Any help is greatly appreciated. Thanks in advance!
