BSOD occurs when computer asleep, involving ntoskrnl.exe

I have an HP TouchSmart 620-1110, running Windows 7 Home Premium edition, 64bit. For the last few days, the computer has been shutting itself down overnight from sleep mode. So far, this only happens when the computer is asleep. I have attached the SF Diagnostic information. My wife's HP TouchSmart 610 was having the same problem a few weeks ago. Desprague discovered a couple of old drivers which fixed her computer's problems. I'm hoping for another miracle for my computer! Thanks for your help.

OS: Microsoft Windows 7 Home Premium, version 6.1.7601 SP 1 Build 7601
CPU: i7-2600 @3.40 GHz
RAM: 16.00 GB
Display: AMD Radeon (TM) HD 7670A Graphics

It seems your Broadcom 802.11g Network Adapter is a possible cause, please update the driver from here - Downloads | Broadcom

I have updated the Broadcom driver as you suggested and so far everything's OK. Thanks so much for your quick response. I will wait a week to see if the problem is permanently fixed and then mark this problem as solved.
