Actually, this problem occurred because I lent it to someone else, it's the second time something like that happens to me because I lent my disk to someone. I tried to use it on other PCs, it doesn't work.
They probably removed the disk while in use without performing "Safely Remove Hardware" procedure. If Windows doesn't assign a drive letter to the disk, the partition table may be damaged. In this case a data recovery software may be the best solution, there're free ones out there such as Recuva and Disk Drill which you can give a try. It seems people have had great results with EaseUS Data Recovery Wizard but the free version only recovers 2 GB of data. You can still use it to make sure your files aren't lost, if you have important documents, it may help recover them too.
Reserve it? AFAIK the upgrade will be free for Windows 7 and Windows 8.1 users in the first year of release, I would wait at least a couple of months before upgrading to a new OS and see how it's been doing.
Are you referring to this, kkck?
Yep, that's it. And the add is somewhat creepy.... specially because I can't seem to get rid of it.
It seems uninstalling KB3035583 gets rid of it, at least for the time being.
Seriously.... I was particularly worried because a few years ago I got actual malware that looked like that (it was passing for a microsoft update rather than a new windows though).
Yup, it may be due to a virus or faulty drivers, memory modules or hard disk. Can you download and run BlueScreenView (x64 version if your OS is 64 bit)? It'll give you a list of dmp files created after the crashes on your system, right click on the most recent one and choose "Properties". It'll open a new window which tells you the driver that caused the crash (Caused By Driver), the driver name may give us a clue.
Yeah, seems so. See this article for an explanation, more features usually require more resources.
