Hi, I'm using win 7 ultimate. My pc configuration is 1gb ram, 160 gb hard disk, asus motherboard with intel core2duo processor. Few days ago when I tried to start my computer by pressing power button it didn't response. I saw the green light was on in motherboard ...... and It has power but it didn't respond. It happened a few times. Suddenly after some time my computer kept restarting again and again. It went worse. I started my pc and it was restarting again and again before it could start properly. Now when I start my computer it's going off or restarted again and again. Pls help me to get rid of it.
