iPC Touch Screen Died & Bad CMOS Checksum

Hi folks

Just got my iPC in from the garage to prepare for a show in the morning.

The righthand touchscreen is not working and I have noticed a different splash screen on the left screen which looks likes like it is a default screen for a graphics card.

After a few reboots it stops booting and says CMOS Bad checksum, and CMOS time date incorrect.

Can anyone shed any light on this as I typically need it for NYE tomorrow!!

Many Thanks
