My laptop’s screen goes black W/ a flickering white line

December 22, 2018 at 12:59:06
Specs: Windows 8.1 pro, 8 gb, Intel Celeron 2.16 gh 2 cores
So, I have had my Acer Aspire E5-511 for about 4 years with no major problems up until now. Recently, every time I restart my computer or if I do a demanding task it goes black and flickers a horizontal white line. The way I fix it by manually turning of my time laptop and giving it some time before using. However, after a while, I comes back. I have tried re-installing my operating system and re-installing my monitor and gpu drivers.

Try/borrow an external monitor & test.

Could be overheating.

It does sound like overheating which is most often a build up of dust. Get a can of compressed air (Dust Off or similar) an blow out all of the vents. See if it helps.

"I have already tried cleaning the vents but it hasn’t fixed the problem"

Did you try this way?
On a laptop, you have to suck the dust out, unless you are prepared to pull it apart.

I used a vacuum cleaner at the vents and the fan

That also looks like bad memory, RAM, try with a new RAM chip and see or maybe the GPU RAM is bad

Processor: Quad-core 4GHz Intel Core i7-6700K (overclocked), RAM: 16GB, 2x USB3, Rear USB ports: 1x USB3.1,500GB SSD, 2TB hard disk, Graphics card: 6GB Nvidia GeForce GTX 980 Ti, Windows 10

This might help

1. Turn the laptop off.
2. Connect an external monitor to the laptop.
3. Turn on the external monitor.
4. Turn on the laptop.

press an "external monitor" button, for the external monitor to work. If the display is fine on the external one then there is a problem with the ribbon cable that connects it.

If there is no display on the external monitor then you might need to get the motherboard changed.

If the external monitor shows the same as the internal monitor then it is not as simple as the monitor or its cable but likely motherboard or CPU related.
The small possibility that the RAM contacts or socket have tarnished and are being effected even more when warm, here is something to try:
Remove the memory from the laptop, clean the contacts on it with a clean soft pencil eraser, remove the dust with a soft cloth and by blowing on them and then pop them into and out of their sockets 4 or 5 times to burnish the sockets. Test to see if this helps.
If this does not help, you will have to decide if it is better to spend the money on a more costly repair or put the finds towards a new machine.
Another possibility is that the thermal compound between the CPU or chipset and its heat sink(s) has dried or been disturbed in some way (maybe a hard bump) and needs to be removed and replaced (thermal compound). This job is a lot of labor and may not help. If you can do the job yourself then it may be worth it but if not then the bill will not be cheap.
