When I changed the driver hardware did not show up in device manger. Even though VGN-FW11s has the same processor,graphics chip the only difference 50 GB of hard drive & 1GB of ram.
The thing is when I swapped the drives in my older Viao VGN- FS315S no problems apart from the graphics chip not rendering but recognises the hardware though. So what next is a hardware problem or a driver bios problem because the drive does not even boot up os software.
I would be very grateful if someone give me some guidedence and tell me what it is.
