Solved! Screen Flashes at random occasion

[Kgy97]

So i have a pretty old laptop (Asus A43SV) and i don't know why it began flashing its screen (even when i am writing this thread. So the flash usually looks like this: 1) The screen turns to black (no lighting on the LCD and when you play something on the background you can still hear the sound). 2) It flashes to the last screen and then flash back to black before go to the newest screen. 3.) The cursor always centered after the screen goes black. 4.) It occurs at random times, sometime it doesnt occur at all and sometimes it happens constantly and annoy me a lot.

Things i've tried:
1.) Almost every youtube advice that i can found (except opening the hardware because i don't have the right screw to open the internal part)
2.) I try to check the refresh rate and it only give me 60hz
3.) Cleaning the insides (i ask a technician to open my internal and clean it)
4.) I tried to overclock my laptop a bit using MSI Afterburner

Things that i don't know affect the flashing or not:
1.) There's a stripped/burned ribbon cable that used to connect the power button
2.) My external Fan that is not good enough

Please do answer this thread ASAP. Thanks!

Try this...

1. Turn the laptop off (not sleep or hibernate but off).
2. Connect an external monitor to the laptop.
3. Turn on the external monitor.
4. Turn on the laptop.

NOTE: You may have to press an "external monitor" button. Could be the f4 button or a button with two monitors on it, for the external monitor to work.

If you can see fine on the external monitor, then your attached display, or the ribbon cable that connects it, are your problem.

If you can't see on the external monitor at all, or the problem occurs on the external monitor as well, then it is probably the graphics card/GPU that is the problem, which may require the motherboard be replaced.
