It will not boot completely. It stops at the windows xp welcome screen and kind of just shuts down - no fans running, nothing on screen. The only indication of power is a blue blinking light behind the power button on the front of the tower. When I try to "reboot" using the power button nothing happens and the light continues to blink. If I simply unplug the power from the computer, the light continues to flash. The only way to get the light to quit blinking & to try to reboot again is to unplug the power from the computer and hold the power button for 60-90 seconds. After that, when the power is plugged back in, it tries to reboot again and repeats as described as above.
Any ideas of what the problem is? I would appreciate any help. Thanks.
