Hi, I have Windows Vista Home Edition and am up to date with all the updates, e.g. have installed Internet Explorer 8 and Service Pack 2 recently. I have also updated Adode Reader, my webcam Logitech software, and my HP printer software.

I have never had this problem before, but over the last few days sometimes the computer is shutting down by itself. It seems to do this more, when I have set the computer to "sleep" after 10 minutes. But I am not completely sure if it is connected to this.

There is another post about "blue screen" but I'm posting this separately as there might be different causes

Any ideas how I can find the cause and resolve this? Thanks.

The correlation with the sleep mode could be correct because 9f means:



So basically, you are probably looking for some hardware that isn't working correctly. The trouble is it could be anything. And although I say Hardware, it could be the drivvers associated with that hardware. Since it is of recent date, the first thing to try is a system restore back to a date before it started. If that removes the problem, prevent things from automatically updating and introduce updates one at a time and slowly in order to pin point which introduces the error.

If that doesn't work, then it is probably the hardware itself so I'd start by disconnecting all external peripherals such as the printer & webcam and seeing if it makes a difference. If it doesn't then you are in to opening up the PC (assuming it is a PC & not a laptop) and stripping it dwn to the minimum i.e. motherboard, memory, processor & hard drive. If you still get the error then it is within that last group. If the error goes, then you reconnect things one at a time to find the culprit.

I'm afraid a lot of work could lie ahead of you............

Thanks for the reply. One solution, is that I could set the computer not to sleep.

I found a program called "sigverif.exe" which checks which of your drivers are signed or unsigned (I typed this into the start menu box). Most of the drivers were signed, some which I could not identify were unsigned. Also BitDefender 10, which we installed recently, has some drivers. Some show up as signed, and some are unsigned. On Device Manager, there is no sign that any hardware drivers are out of date. So it could be software drivers....

Maybe with the drivers for the new version of BitDefender, and/or other recently installed software, there are some minor bugs. I don't have the expertise to sort this out, so may have to put up with it for the moment. :-)

I don't want to do a system restore, as it is too complicated. I am sharing the computer with my parents - it is their computer, and it might not go down well. I think it is software related because we've updated software recently (Internet Explorer 8, new version of BitDefender....) but there have been no changes to the hardware.

System Restore isn't complicated. I'm talking Windows System Restore not running any sort of restore disc that came with the PC.

System Restore doesn't affect your data and is reversible. If it is software related as you suspect, it will probably fix it.
