I have ASUS G60J Notebook (info here), what happens is next:
I'm using it to code and design some websites and for some random playing.
The problem is occuring randomly so it strikes whenever it wants, let's say I'm watching a movie located on D: drive , the movie stops and VLC show's an error that there is no movie to play.
When I open "My computer" I can see that my second HDD is gone and I can't bring it back without restarting windows.
The same problem is happening with my DVD-RW and my USB cam, they just dissapear whenever they want to.
The only fix which is working now is manually enabling the devices in "Device manager", but I can't enable the HDD like I can do with cam and dvd drive.
Does anyone has the same problem? Is this maybe a virus?
I'm running : Windows 7 X64 Home edition with Avast antivirus, windows defender and Game booster.
My guess would be this is less a virus and more a system driver issue. If the computer is new and still under warranty I would take it back and have it serviced, if not I would try updating the bios and anything else you can on the asus website.
