Freeze

[RawkBandMan]

I am quite baffled by this.

A couple days ago, I was testing out my livestream on a variety of games, and I opened up Amnesia. I clicked on the custom story, and everything worked fine, the story loaded, I played, when something weird happened.

I went into a room, in which I had been in before, and was looking around for an item to pick up (mostly oil), when my entire computer locked up. I was pretty confused and thought it was just my game freezing, until my screen went black. I panicked and clicked CTRL+ALT+DEL, and my screen reappeared, and it took me to the little window that it takes you to when you click that combination of buttons, and I clicked Cancel. I was able to use my computer then, and my mouse went out of my screen and I could click Firefox and my livestreaming program alright, but Amnesia was just a white window, and when I clicked on it, it told me that Amnesia.exe has stopped responding. I closed the program, and everything worked normally, but I noticed my Skype background, instead of being the navy blue it should be when you are in a call, was grey.

My friend had told me it happened to him on his old PC, and it was a graphics card issue, but I don't think that is the case, as my PC is a little more than 2 months old, and all the parts are brand new.

If anyone could give me some insight on why this may have happened, I would love to hear it.

If you need any other info, feel free to ask. Thanks guys ^^
