Okay, I don't know if this is a hardware or software problem.
My friends laptop is running Vista and he's had it for a little over a year now. He's not exactly computer savvy, (he had over 2GB just sitting in both his recycle bin and temporary internet files for months) but his computer is having a really weird problem.
He decided to start cleaning up the space, defragging and uninstalling unused programs. He definitely freed up more than 10GB, but his computer only reads that it freed up 2GB. And with every restart, it changes drastically. From 6GB to 300MB. I seriously have no idea.
Any ideas? I can give more background info if needed.
