Recently (for the last few months), I've been having a problem where if I sleep/hibernate my laptop (Dell XPS 15), whether that be by shutting the lid or manually, upon waking I receive a BSOD after 5-20 minutes. The message presented is a DRIVER_POWER_STATE_FALIURE. Interestingly, until the crash my USB ports also stop working completely.
I'm running Windows 7 Home Premium x64, which is NOT the original install, but a new one made from a retail CD. I installed this straight after getting the laptop (July 2010), and had no problems until mid-March.
Any help would be appreciated, I can provide any information I've missed!
