Is there anyone out there has had experience or can advise on the following problems I am experiencing with my Acer 1644. The laptop went into standby mode and blue screened, I have tried to boot up in safe mode with command prompt.

I would say before going any further the hard drive is split so there is a C: & a D:, the C: When the laptop tries to boot it tries going into the D: only. I have tried going into BIOS and setting the first boot device to CD drive, this too has failed to get the desired outcome. The CD drive does not appear to be recognised either. Can anyone point me in the right direction on how to resolve these issues ?
