I am new here so i apologize in beforehand if my grammar is bad, i seem a little rude or my descriptions are not very clear.. So i've been getting this error message thingy lately after turning my computer on and i can't turn the computer off without holding the power button, it just stays in the "shutting down" screen. This started after i uninstalled quite a few programs including Norton antivir without restarting and clicked then the "install updates and shutdown" (latest Vista update) orwhateveritwas button. Next time i turned on my computer it said that the computer couldn't be started and asked if i want to restore it to the moment when everything was okay and i did. All the programs were still there and the update wasn't installed. I thought everything was okay until i tried to shut down the computer. After over 15 minutes of staring at the "shutting down" text i just manually shut it down. After loggin in an error message was there. I tried to look for solutions but the window just disappeared. This has now happened many times. Also i can't wake my computer from sleep, it just freezes. I did some research (google) and ended up trying to understand the minidump file. By now i know only that it should be driver(s) causing problem.. The only sensible part for me was this. DRIVER_POWER_STATE_FAILURE (9f) A driver is causing an inconsistent power state. Arguments: Arg1: 00000003, A device object has been blocking an Irp for too long a time Arg2: 82d7d1d0, Physical Device Object of the stack Arg3: 87180030, Functional Device Object of the stack Arg4: 83417318, The blocked IRP Well, i checked if i have any unsigned drivers which could cause the problem and there was one.. xrwcxst0.xst. I haven't got a clue what it might be or what i should do now. Im already panicking. I can find similar cases but they're well.. still different. So what im asking is help as soon as possible. Oh yeah... I have an Acer TravelMate series 5510 (5512AWLMi) with Vista Premium. The dumpfilethingy should be attached..
