Starting about 4 weeks ago I've been encountering a frequent (every day or two, twice today) blue screen when putting the computer in either sleep mode or hibernate mode. I have not added any new hardware or installed any new drivers in this timeframe.
Here are the two minidump files from today uploaded to SkyDrive:

I'm running a Toshiba laptop, L645D-S4056, AMD Turion II P540 Dual-Core Processor, 4.0 GB RAM. I have the power setting selected to "high performance" with the computer set to automatically enter sleep mode after 1 hour (display dims after 5 minutes and turns off after 10 minutes). The compter is also set to enter sleep mode when I close the lid. Sometimes the blue screen appears when I manually put the computer in sleep mode, and sometimes the blue screen appears when the computer automatically enters sleep mode after 1 hour of inactivity. Other times it functions normally.
Here's the latest crash info (two today so far):

Any assistance that can provided would be much appreciated. I have been using sleep mode and hibernate for several years on this computer with no issues whatsoever. I really need to be able to continue to use these two functions.
Thanks.
