That's the strange thing. Nothing shows. The software I'm using to test shows the CPU usage at about 30% now (was over 50%). Task Manager and Resource Monitor show similar but can't find anything in processes that is causing it
edit: it's gone back to around 50%!
edit 2: changed the duplex to 100mbps and increased speed by a lot and decreased CPU usage down to around 30-40%. Not perfect but definitely better
edit 3: This is no good. Tried everything including safe mode but the CPU usage remains high! All other PCs here are XP and performing the tests on all of them give the same results, 1%. The Win 7 PC averages around 30%. I don't like it at all.
