satellite L755 suddenly turned off.

i have laptop satellite l755 that i bought it 3 years ago. while im playing games, it suddenly turned off by itself and the orange light blinking then i cant turn it on back. if i want to turn it on, i must unplugged power source first then turn it on again to boot my laptop.. any idea about my problems?? btw, i also got problem with my laptop's charger or AC adapter.. is my "suddenly turned off" problem caused by my AC adapter or my laptop chipset?? hope can solve it.

I would try a new AC adapter. I have an older Satellite that gave me a similar problem and it was solved by replacing the AC adapter. It would be the least expensive thing to try first.
