Hello folks, i recently let a friend of mine borrow my optical drive for his new build and got it back the other day, after installing my new motherboard (Asus Maximus Hero) and cpu i7-4770K, i needed my optical drive back to get software for my new parts, i plugged it back in, i booted my pc up my pc and everything seemed fine until i noticed that my external hard-drive was not showing up (i diagnosed that by unplugging it from the power supply and plugging it back in) but when i did that it seemed the problems started, i went to put my asus mobo driver disk in and as soon as i opened the tray the optical drive vanished from my computer, thought nothing of it closed the tray but the disk wasn't being read, so i thought oh there must be a driver problem,i rebooted the computer, the drive came back up again, i installed the latest driver software, and the drivers that were on the disk i left in the drive, everything seemed okay until i went to install World In Conflict then all of a sudden when i opened the disk tray yet again it vanishes off my computer.. I've tried the regedit method of deleting the lower filter and higher filter but still not sorted it out :/ anyone else had the same problem and can diagnose it? it's doing my head in and would really appreciate any help p.s sorry for my long winded post, this my first ever post on here.
