  1. Ok so when shutting down my computer it seems to hang at shutting down for ages (time changes) and then I get a BSOD and it says DRIVER POWER STATE FAILURE. It also does this randomly when not shutting down.

    I have a Dell XPS, Core i5 (2.4ghz), 6Gigs of RAm, running a legal copy of Windows 7 Home Edition (64bit).

    Its fully updated and have previously done a reinstall.

    Music also gets stuck in between sometimes

    I have attached zip file required for analysis

    Anything would be helpfull.

    Both errors are the same 0x0000009F: DRIVER_POWER_STATE_FAILURE
    A driver is in an inconsistent or invalid power state. Typically occurs during events that involve power state transitions, such as shutting down, or moving into or out of standby or hibernate mode.

    Both cite the same driver NETwNs64.sys as the cause of your system crashes. This driver belongs to your Intel Wireless WiFi Link Adapter.

    Go to Dell's website, find your exact model and then download and install the latest WiFi drivers/NIC drivers for your system.

    In some cases the driver causing the problem is not the one named in the crash dump. Sometimes it can be something that you would least expect causing the problem.

    What security software (Anti Virus, Anti Spyware, Firewall) do you have on your system?

    Have you added any security software to the system since you bought the PC or added any other software just before the BSOD's started to happen?

    You have mentioned you did a reinstall and you have only had this PC since February.

    Why did you do the reinstall?

    Have you had a problem with this PC since you bought it?

    Taking into account that this PC is new and that you haven't changed anything that is installed on it I would therefore suspect the problem is due to a hardware fault.

    You should have a warranty with a new system so I would recommend you return it to the supplier for repair.
