Critical error - Event ID 41 is (most likely) when you forced the system to restart (usually by holding the power button down).
You have a NETGEAR WG111v3 Wireless-G USB Adapter:
I do not recommend using wireless USB network devices. Especially in Win8/8.1 systems.
These wireless USB devices have many issues with Win7 and later - using Vista drivers with them is almost sure to cause a BSOD.
Should you want to keep using these devices, be sure to have Win8/8.1 drivers - DO NOT use Vista drivers!!!
An installable wireless PCI/PCIe card that's plugged into your motherboard is much more robust, reliable, and powerful.
I noticed that you don't have Secure Boot and/or UEFI enabled. If you were having problems with it and changed it, please let us know.
It's not necessary to enable it now. But, should you reinstall Windows at some point in the future, please enable it first.
I mention this because it may happen that (one day) the system won't boot. This can be caused by a program changing your UEFI settings, or an update of the UEFI resetting it to default values.
To test and see if this is the cause, boot into the UEFI and see if the settings have been changed. If uncertain, try with Secure Boot both on and off (and the UEFI on UEFI or Legacy (CSM))
If it still doesn't boot after trying this, then move on to other troubleshooting tools as it's not likely to be due to this.
Black screen errors are notoriously difficult to troubleshoot. Let's start with this stuff:
- update chipset, storage, Intel, video, wireless, Bluetooth drivers to the latest, Win8.1 compatible versions (DO NOT use Win8 versions, only Win8.1 - if unable to find them, post back and we'll see what we can do).
Also, please do the following:
- open Event Viewer (run eventvwr.msc from the "Run" dialog))
- expand the Custom Views category (left click on the > next to the words "Custom Views")
- right click on Administrative Events
- select "Save all Events in Custom View as..."
- save the file as Admin.evtx
- zip up the file (right click on it, select "Send to", select "Compressed (zipped) folder")
- upload it with your next post (if it's too big, then upload it to a free file-hosting service and post a link here).
