Resume from Sleep or Hibernate Locks Event 41

I have a customer's machine in my possesion. He is running Win 7 Home premium on a recently upgraded Toshiba L355-S7825 Laptop.

The machine runs very well, until it is brought our of sleep. After about 40-60 seconds it will freeze completely. Forcing a cold boot after which it will run fine again, until sleep is invoked again. This is repeatable 100% of the time.

Event logs show Event ID 41: Kernel Power Critical error. I have updated Bios, and drivers from Toshiba's web site. All to no avail.

I have search this site somewhat at length, many google queries have landed me here in my research to determine what could be causing this. Most of the results I have seen involve some type of driver conflict with the sleep suspend/wake features. My customer has told me do not put Vista back on the machine.

It would be nice to solve this one however I am stumped at this point.

This machine was running Vista Home Basic, and never had this problem before. I can log in from the laptop and provide the minidump if someone thinks that it might help.

I actually experience exactly the same on a custom built HTPC with Windows 7 Home Premium. Using DVBViewer as the TV program, the computer resumes from sleep and starts to show the live TV. Then, after 30 seconds to approx. 3 minutes, it freezes and I have to unplug it before I can restart. This also happens when DVBViewer is not running, i.e. it's not the specific program that causes the freeze.

Here the eventlog for the situation:

Any idea?
