Hi I have a strange issue. I built a computer for my freinf which had win 7 ultimate on a gigabyte motherboard. It also included a sony optiaric 726 DVD drive. At first it installed with no problem. However it now goes through periods where it is not seen by win 7. If i boot system into bios, the drive is seen. Ocassionally Win 7 sees the drive and "loads " the drivers, then after a while , it no longer is seen so that I cannot use it. Any ideas ? Thank you
