Recently my MSI laptop was blue screening with messages like Memory_management, about 5 different ones, since. My antivirus had just ran out and it's a perfectly good laptop I came to the conclusion I was hacked. Therefore I went to completely reset my laptop to factory settings and I noticed the reset loading bar went to around 34 ish % and jumped back to one, I left it resetting overnight to see if it would eventually work and I found it the next morning with "There was a problem while resetting your pc" and now I find myself starting up with automatic repair followed by a menu with continue using windows 8.1, use a device, troubleshoot and turn off your pc. Continuing sends me staaight back and no other options seem to work. I've looked around on the forums but I can't find any solutions that work. Note my loop came pre-installed thus I am without a windows 8.1 installation disk and do not know If installing windows 7 (not exactly a legit copy) will void the warranty.
