No No it's fully installed Windows but when I actually transfer files from an external hardrive, things like music and my photos. The computer will rather blue screen when it start transfering or just reboots as soon as I plug the external harddrive.
I installed this Western Digital Caviar Blue WD5000AAKS 500GB formatted into my other desktop and works fine without any of the error of "not detecting but still going to windows issue." Also can transfer files fine.
Probably an motherboard issue.
