From time to time, my computer hangs up and when I move the mouse a fluttering sound comes from the tower case. The system consist of FIC AZ11E mobo, AMD Duron 850, Maxtor 40g hd, ATI Xpert 128 16mb graphic card, Teac 12x10x32 cdr-w, 128mb PC133 SDRAM, 56k U.S. Robotics modem, 52x cdrom, Microsoft internet keyboard, Microsoft wheel mouse, Creative Soundblaster Live sound card.
The last time the system hung up and the mouse made weird noises I was online and checking my email in Outlook express. Alt+Ctrl+Del wouldn't even bring the Close Program Dialog box up. I had to Alt-Ctrl-Del a second time to reboot the system. Since then I haven't been able to make it happen again. What causes the system to lock up and the mouse make weird noises? I did run Norton Utilities and it found some problems within Windows and it repaired all of them. One problem was with DirectX and it said that the problem could cause the system to hang up and some applications to not work properly. But I would like to know what is happening when the system hangs up and the mouse starts making weird noises.
