Few weeks back I purchased a new computer with the following config :

AMD Athlon 64 X2 Dual Core Processor 3600+ 1.91 GHz,
512 RAM , 160 GB HDD etc

I a having Windows XP in this system.

Now the problem is that , it restarts sometimes without any effect.And if it is kept without working for 10 to 20 minutes its becoming hang.

What can be the reason.I am new to Athlon.
