hello again, I try to reset CMOS setting by remove for 30 mins. then when I plug the power cable the fan start automatically as always but it continue restarting for several times by itself b4 I press start button.
i shut the PC down forcefully and try to start I gain for few times, but finally the PC stop start (like dead) the fan also stop. only the power on button blinks red light. even after I remove the power cable, the red light blinks for around 30 sec.
and when I touch some external part of the PC it has a little shock.
this is not the first time when I try to change the hardware, I always discharge myself b4 making any change. this is so strange to me
