It flickers on starting or restating. This is what happened:
I installed Windows 10 Pro. It was failing to restart when I download and install new applications. Then later on, the pointer of touchpad disappeared, then I fixed it, it's now working. Then I changed and installed Windows 10 32 bit, that's when the flickering issue started. I then installed Windows 10 64 bit, still it's flickering. Then I installed Windows 8.1 Pro, but still it flickered. Then I reinstalled Windows 10 64 bit, which I'm currently using now, and it flickers still.
It flickers when starting, it flashes 2 times, then after that it works fine.
Please help me with this issue in solving it, I've tried all I can. I want it to run normalyy and smoothly.
