I have been having a strange problem the last few weeks which has been getting worse. When I turn on the computer, windows XP gets to the desk top but gets stuck before loding the icons. I have to turn the computer off and on about three times till I get through to the icons. I have the blue task bar on thye bottom, also without icons. The icons load with the safe boot. I have run my McAffe scan anfd there is no evidence of virus seen. What can I do? Please help.
