I bought this PC a year ago, It was fine. Then the DVD-driver got broken, It did read, but only for few minutes at a time. That was changed to Optiarc 5200S. I installed it, Windows Vista did install the drivers, but this one won't work at all. The led-is blinking and disk is rolling for some time. If I try to double-click on the driver on the My Computer-window, it will stuck and stop answering. Only solution is to reboot. Same if you insert a disk and open a media player, it will stop answering.
One weird thing is that if you have a disk inside when you start PC, the operation system won't start. Only black screen appears. The HDD is set above the DVD-driver in the BIOS.
I tried to update firmware and motherboard-drivers. Any ideas?
