Due to persistent overheating problems, my laptop is finally dead. I have to assume that it was hardware issues that eventually caused a corruption of the data on the C:\ drive, as I have no other explanation for it (virus and spyware free as it was). It won't boot up properly; checkdisk finds "unspecified errors" while trying and skipping checkdisk only works about 50% of the time. If I do get it to boot it will either freeze or restart on its own within 15 minutes of operation.
I've taken the easy way out with a trip to Best Buy and an extra load on my credit card (which will at least slightly impact my paying off my debt). This alleviates my immediate issue... that I was already two days without internet access. I'll be able to pick it up tonight. Now I just have to figure out how to get some data off of it (nothing crucial, but all "nice to have" information, pictures, etc.)
And maybe figure out what to write about next.
