Device status:
This device cannot start. (Code 10)
{Operation Failed}
The requested operation was unsuccessful.

I tried disabling hibernation and re-enabling it, but that changed nothing. what tools can tell me which device or driver is causing the problem? happy to post reports here if someone can help me read them. id especially like to know whether I sholud go back to the older chipset package or try the one from my PC maker instead. seriously need help here 馃槶
