whea_uncorrectable_error

Looking for some advice.  I have been receiving this error message followed by a restart and an error report being sent.  I have noticed it mostly when scrolling through web pages but recently it has happened shortly after a restart (before I managed to do anything).  Just looking for suggestions as the machine is still under warranty and I would like to know if it could possibly be a hardware issue.

Spec is:-

XPS8500

Processor: - Intel Core i7-3770 CPU @ 3.40 GHz

Installed memory:- 16GB

System type:- 64 bit Operating System, x64-based processor.

Graphics card:- AMD Radeon HD7800 series.

Windows 8 Pro with Media Centre

It was bought just as the base unit and I am running dual monitors via displayport connections.

Thanks
