My computer will no longer wake up from sleep mode at the
touch of the mouse or keyboard. I now have to reboot. I
have reset the bios for power management to original
settings and optimised the settings in the bios but no joy.
 
Have you changed keyboards or run any updates recently? You could attempt to restore Windows to a prior state using System restore to see if this fixes the issue.

You should also to see in BIOS that 'wake-up' events include Mouse / Keyboard.

Should you fail to achieve this, then instead of Sleep Mode, try Suspend Mode. This effectively writes the current system state to the Hard drive and this file is read when you turn the PC back on. It takes around 25 seconds to have a fully operational computer.
 
Actually, there are two main sleep states. There is S1 and S3 that are
the most common. S1 is Suspend and S3 is Hibernation. In S1, the CPU
usually stops, the DRAM is refreshed, and the system is in low power
mode. In S3, the CPU has no power, the DRAM is in a slow refresh state,
and the power supply is reduced in power. These are different for each
computer, but what generally happens is in Suspend Mode, the memory
keeps all of the info and the system wakes without loading anything
since it is still in the memory. In Hibernation, the memory is saved the
the Hibernation file on the harddisk and then Windows is resumed by
loading that info from the harddisk to the memory. This takes much
longer and is more difficult to wake the computer from.

I would suggest trying Sleep Mode and make sure that you have the proper
settings in the BIOS as well as in Power Options (and maybe keyboard) in
the Control Panel. Note that this will usually not work with Wireless
keyborads, but usually only works with PS/2 Keyboard or supported USB
Keyboards.
