Not on this computer but another. It's some weird thing that supposedly caused a program to not work like it should have, but then it got progressively worse. Not only did the program itself start messing up, but supposedly the entire computer looked like it was restarting and then it acted like it was a blank slate, with only internet explorer and the recycle bin with every other file on the desktop being completely absent. After turning off and turning on a number of times, everything supposedly went back to normal. However the case is still very suspicious to say the least. I want to say that hopefully everything is simply just having trouble due to the recent cold and possible power effects, but I'm worried that it might be far worse. Any ideas on what the hell is going on?

maybe some windows recovery function or boot on windows safe mode.

but if you are too scared or want to be on the safe side, just format and reinstall your pc.

Agreed. I had this problem on one of my PCs, SHortly after that most of my data became corrupted, I ended up loosing everything on that drive. Thought for me it turned out to be bad ram. as the machine(Same HDD) runs perfectly fine and stable.
