Strange laptop problems

[Vishes]

Hi
I have an Acer Aspire e5 572g that some days ago stopped booting. Removing the AC and the battery then holding the power button for 60 seconds worked but then the screen started flickering and the laptop going to sleep. I changed the setting in power options to never go into sleep mode but the flickering didn't stop. The laptop still had some booting problems but was somehow usable.
The problem is that now it won't boot at all, what could be the cause and how can be fixed? Please help.

Hi,

The flickering problem can be an indication that it's either a bad LCD or the GPU is starting to fail. Here are some troubleshooting steps that may help.
- Start by doing a hard reboot, remove the battery and unplug the AC adapter then press and hold the power button for 20 seconds then try booting it up again.
- If this will not work, do test the AC adapter if it's working properly. Remove the battery and power the laptop with just the AC adapter connected and see if it will boot up or not. do also try a different AC adapter that has the same voltage and see if it will work or not.
- Proceed with reseating the RAM's if trying a different AC adapter will not work, remove them all for couple of seconds then put them back in making sure everything is seated properly.
- If it will still not work, connect an external monitor and see if you'll get any display from it. If there's a display on the external monitor that could mean that the problem is the built in display.
- But if there's still no display on the external monitor that means the problem lies in the motherboard.

Tryed all of those things and nothing helped, so it's probably the motherboard. Can that be fixed or it needs to be replaced?
