Delay in saving every sheet in Autocad 2014

[234627]

Hi,

I am facing a problem in Autocad 2014 which was installed in Windows 7 OS.

Whenever i try to open a sheet in autocad 2014 there will be a normal delay but if i try to save a single sheet by command (QSAVE or Ctrl+S), Autocad will go for long process for saving the sheet more than 15min and unable to do any other operations in the CAD.

Please help to solve this issue which delays my normal activities in Autocad.

Thanks.

Are these originally 2014 drawings?  Are they from a vertical (C3D, MEP, etc..)?
