I wasn't really sure where to post this, so I decided here works--
I started having this problem a few weeks ago, I'm not sure if there was a specific event that might have made it start... if there was anything, I don't remember. I use a Dell XPS 13, with Windows Vista.
Basically, when I try to download anything at all-- it appears to download but I can't access the file, it simply does not exist on my computer. I've searched, done system-wide searches for a file I made, emailed to myself, deleted, and then tried to download from the attachment- nothing. These things I've downloaded show up in the Recent Items menu in the start menu, but if I click them there, I get a popup that says that Windows is searching for the file. They don't show up in the recent downloads folder.
This problem happens when I download from the internet, and it doesn't seem to matter what file type, or browser, or anything. It's the same whether is a link on a website or an attachment in an email. I've tried word documents, pictures, .wav files, a Dr. Scheme file (thats when I first noticed it)... in both Internet Explorer and Firefox. I've saved them to different locations- my desktop and specific folders, and they download, but then they're just not there. I can open a word document from an email attachment and then save, but I can't save to a location during the download itself with out the file subsequently disappearing from my hard drive before I can even open it. The only thing that has worked is if I download a file through Skype or AIM, etc, it downloads no problem. I can also transfer from a flashdrive with no issue.
I go to a specialized math and science high school, so I have legitimately computer geeky friends- they're stumped as well, and even my computer science teacher has never seen this before. One friend thinks it has to do with an internet setting not accepting any files, but doesn't know how I would fix it or anything.
Can anyone help me?? It's really inconvenient as I often need to receive files sent out by class partners or teachers.
