Black screen and caps lock button blinking while powering up

[drg555]

While trying to turn on the laptop, after pushing the power button, the button itself lights up as normal but the screen does not turn on. At the same time capslock button flashes 5 times slowly followed by 3 times fast blinking and the process repeats itself. Eventually the laptop powers up (after 20 or so times trying) and works for a while but when i turn it off an try to turn it on the next day the problem occurs again. Suspecting the motherboard or something similar because the laptops motherboard died but was replaced under warranty. Still has about a year and a half of warranty.

Seems to be a failed motherboard. (Second one in less then 6 months)  Something is very wrong with omen laptops quality check. First two 15 inch models i ordered both had dead pixels (i7 7700 HQ & GTX 1060 models, 8GB RAM, 256GB m.2 NVME SSD), and the retailer offered to replace them with an upgraded model (17.3 inch i7 7700HQ & GTX1060 , 16GB RAM, 256GB m.2 NVME SSD, 1TB HDD) which had a bad screen bleed issue. Took it in for repairs, they supposedly changed the display but it still has a pretty bad screen bleed. My brother bought the newer model (the one in question, i7 8750 &  GTX 1070) which burned two motherboards in around 6 months.
