3 option,
1) check ram, test ram lain kat mobo yg same, n test ram yg same kat mobo yg lain.
2) test hdd by run checkdisk, buat dl dos. 3) if hdd ok, try buat repair windows
3) if hdd still problem, try reformat. normal installlation, test utk 15minit utk check results.
4) if masih dlm keadaan same, meaning mobo ada problem, bole send warranty kalo sanggup tunggu
atau bli board murah utk testing smentara. kalo tak brani bli, test kat kedai utk keselamatan duit.. atleast kluar pon tk byk sgt.
selamat mencuba yea
