I have an approx 2.5 years old G551JW notebook which suddenly shut down 2 months ago. I tried it to turn on , but it shut down immediately after the power button light come in (But it sounded like something started for a sec inside the laptop ,maybe a vent). I removed the rams, and inserted only one back, and after that it stayed powered on, but i dont't had any screen, just black screen (maybe the screen backlight turned on , i dont remember), the keyboard light don't worked then. After few weeks i disassembled the laptop because i needed my msata to make a backup. After remove msata, and assemble back computer , i tried it turning on, and after that it's turned on , worked the screen , the rog logo appeared and it searched for boot media. Next day I installed an older sata HDD and tried to install a windows, but during the windows install (after approx 10 min powered on status) it shut down and if I tried turn it on , it turned off after the power light came in. I leaved it for a few weeks again , and after that it again turned on, but after a few minutes the screen flickered and turned on. Do you have any idea what can I do ?
I'm almost sure it's motherboard issue , but I hope anybody seen this issue and have any experience with it.
