Windows shuts down instead of sleeping, sometimes gives BSOD

Hi, I have been googling around and can't seem to find an answer that helps my case, pretty much my computer has been shutting down instead of going to sleep and when I start it up again it said windows didn't shut down properly, the first few times it gave me a BSOD stating DRIVER_POWER_STATE_FAILURE but it stopped giving me that. For some reason my computer doesn't create minidump files or dump files at all, I've read the 'How to configure windows to create dump files' and made the changes listed in the tutorial and I even downloaded the registry file but still nothing. It only happens when I've had it on for the day because if I restart it and put it to sleep within say, an hour, it will go to sleep properly but if it's been on for the day then I will hear some component in my computer turn off but the fans will keep running for 10 minutes until it switches off.

It used to only happen every now and again but it happens every night now, looking forward to your help :)

Hi, thanks for the response. The reason there isn't a crash dump attached is because my computer just doesn't want to create them. I downloaded the REG file a while and still no luck, I followed the tutorial on how to produce them but my computer still wouldn't make them, I made the page file bigger than my installed ram but still nothing. Last night though I used Command Prompt to disable hibernation and my computer successfully went to sleep so maybe that was the issue, I'm hoping that it is now fixed since it has been weeks since my last successful sleep. If it shuts down again I'll post back here with the memtest, stress tests and speccy screenshot. I will uninstall the LogMeIn driver now just to be safe. Thanks for your help I was thinking I might have to take my computer to a technician which I have never had to do.
