Random crashing problem

[Wedge]

Hi,

New PC, new install of windows.

Crashing randomly causing immediate re-boot of system.

Was worse before, thought it might be caused by a USB device but not sure now.

The error details are:

BCCode : fe BCP1 : 00000005 BCP2 : 8660E0E0 BCP3 : 10397001
BCP4 : 856BA590 OSVer : 5_1_2600 SP : 2_0 Product : 768_1

C: \DOCUME~1\Owner\LOCALS~1\Temp\WER4854.dir00\sysdata.xml


Anyone got any ideas?

Many thanks in advance
