I have been having problems with my laptop overheating and shutting off. And today it would not turn on like it usually does.. it just showed me a black screen with white writing. I did some research and it seems to be a reoccurring issue with the Acer Aspire. I have been making sure it isn't sitting on a surface that blocks the fans and ventilation. So my question to you is, what can I do to stop this from happening? I am afraid someday soon it will just not turn on again and I'll be screwed.
