I have a strange problem which has only started occurring since installing BNW, my Pentium Dual Core, 2.7GHz, 2.00GB, ATI Radeon HD 4800 PC starts making clicking sounds when playing only this game slowly increasing in volume until the computer suddenly switches off / powers down. I though it could be the hard drive so run a sea tools test and it passed ok, also have done a chkdsk & updated graphics drivers with no fix. Any ideas what might be causing it? Thanks.
