I'm posting my issue in both places (Windows 10/Crashes + Malware) as I'm not sure what the problem is being caused by, but I've been using BleepingComputer as a reference when it comes to my DIY PC repairs & problem solving (which has very likely led me here, as a registered user asking for help).
I purchased a laptop from Fry's Electronics mid August 2015 for my return to school & classes this fall. I have used the laptop with little problems in the past month, however I have encountered A LOT of issues in the past week. Excel & Word documents causes PC shutdowns, & Disk Usage (per the Task Manager) ~100%.
Backstory & My plea for assistance:
1. Laptop that was purchased was a floor model so it came with applications installed already (as well as "Fry's Electronics" admin user name which I have yet to be able to change).
2. Originally, I had installed my legal & purchased copy of Office 2010. For class assignments & as a general requirement, I was forced to look into Office 2013 (which is no longer available!). I have recently purchased Office 365 & have all of Microsoft Office 2016 installed. This is where my problem begins...
2a. I have been unable to set these programs to be the default when opening similar .doc/.xls documents (as in Start --- Documents --- C++ Programming 120 Homework), & have ONLY been able to open these documents with the Microsoft Office application open (Within Word 2016, I can open any word documents on the PC, but those documents cannot be opened unless you're opening files from the Word 2016 program.)
Since this time, I have had probably 40 laptop crashes in the past week. Many hours lost on assignments that were lost in the crash. Many frustrating occurances in class, while taking notes, where 45 minutes of lecture notes are wiped out due to a crash.
Disk usage hovers around 100% often, & to be quite honest I spent a lot of money on this laptop (>1000$, 16gb ram 1tb hard drive etc) so you can imagine the frustration that despite the investment I have been unable to rely on it when needed.
I am familiar with the process, although I do not currently have any of the tools used for these diagnostics downloaded onto my laptop, I will do WHATEVER is necessary to resolve this problem. The fate of my college education depends on it!
Thank you in advance for your time.
PS: Busy schedule, & I will attempt to check this regularly, but I'll need instruction on how to set up email notification so I don't allow assistance to go without response for very long. Thank you again, and I apologize for my complete lack of appropriate terminology.
