I have Windows2000 Professional, Asus motherboard with Pentium 1 G. It has run ok long time, but something happened. When system boots it has no any icons, no taskbar, no start button, just only clear nice blue desktop, not blue screen of dead. I can hear sound playing when windows starting, but nothing never coming to screen. If I going to safe mode, it shows eplorer.exe in Dos command console, but if I trying to close it , it never finish booting to safe mode. I dont like to format harddrive, is it any way I can fix that problem?
