I have a Pentium 4 3.0 GHZ processor with Intel 865GB Motherboard, 512 DDR RAM of 400 MHZ, 40 GB HDD, NVIDIA GFORCE MX 4000 AGP card, Frontech Smart Pen graphic pen and other computer accesories using Microsoft Windows XP professional. Its a new machine and worked well for about ten days. But now it hanging many a times for no reason. If I am using the computer, the computer hangs (mouse pointer doesn't moves nor does keyboard respond). If I move my mouse vigerously instantly when the computer hangs (pointer stops moving) the computer anuls the hanging and runs OK. But if the computer is not used instantly after hanging the only solution is to restart the machine. If this restart is done many a times, after four or five attempts the monitor doesn't shows any signal nor does the computer starts (I can hear the rotation of parts of the CPU, but I can't hear the startup music, so I guessed it didn't started). If my specifications aren't sufficient to guess the problem I can describe it in details. Please help me.
