in safe mode works perfectly,soon as I try to boot in normal mode it's keep restarting.on screen I don't see any line vertical or horizontal picture look normal on safe mode.but unable to start normal it just restarting over and over.I try another HDD but same things happen,I replace memory but still same.works ok in safe mode but not in normal mode.I will try to post system error report.
