NOTE: These instructions will only work on an Android OS device. If your device runs Windows, then you need to post in that form.
The reset you did, was it the one to keep your files on the device? If so, that won't really clear up any problem if it is software related. You would need to do a full "Hard Reset" for that. First, however, I would suggest trying to start it up in "Safe Mode" and see if it will load. If it does, then while in there save all your files (photos, music, contacts, browser favs, etc.) to somewhere safe off of the tablet. Computer, google account etc. Note: This is only files, apps can't be saved. Then do a full "Hard Reset" of the device to restore it to its original state when you got it. Then you can reinstall...
