Hi… anybody got advice on this one! Splashed the cash on a new PC from DELL (9150 - Intel® Pentium® D 930 3.00GHz Dual Core), broadband - the whole 9 yards. Anyway now find problems with erratic behaviour and DELL support off for the weekend. Basically one CPU core running at 50%-60% all the time and maxing out at 100% for long periods. Task manager reports system idle process taking 99%. (???????) When Core (1) maxed to 100%, system becomes unresponsive and erratic behaviour from mouse etc etc. Anybody any ideas? Thanks for anything you can offer
