hi, i am having the exact same problem, and cant seem to get my head round it.... ...surprisingly, the problem also starting happening after i formatted my XP machine, and re-installed XP. was perfect beforehand... i have an AMD Athlon 64 X2 Dual Core Processor 4600+ although i have the dual core optimizer installed already so that isnt the problem for me i really cannot understand it, all drivers instaleld properly and up to date...it should not be doing this
