Hi I sort it out !
I sent the case over to the company and 'ey told me the truth of of matter by testing it.
They said,it was due to some glitch of "power cable" that didn't work out so well and cause the accident.
They changed the PSU and gave me a brand new "power cable" and It works so well right now.
hi. I have a problem similar to yours that you can read it here: http://www.tomshardware.com/answers/id-2121442/system-rebooting-repeatedly-startup-fans-working-shut.html#13207455
do you think my problem could be about PSU either? which cable did you replace?
thanks for any help
