Specs: Windows 10
For sometime now, when i turn it on and am surfing the net, or playing music or doing any other activity on the screen, before am aware, the screen light will blink briefly and go blank or black. strangely enough, the activity am performing will be ongoing on the desktop, upon a closer look with flashlight. Am very worried about this. what should i do?

Please help me out. Thank you.

If the system is running and the LCD is showing progress when you light it up then the monitor or its contact to the cable or cable itself is bad and your back light (LED) is quitting on you. You can try the almost closing the laptop to see if it lights up again which would indicate a bad cable at the hinge. You can open the laptop (or get service) to see if the ribbon cable is properly seated at the motherboard and behind the monitor. If neither then the monitor may be bad.

You have to be a little bit crazy to keep you from going insane.

I had a Toshiba that had similar issues. Its problem was a faulty display cables.

I don't need to be right, but I am never wrong.

If it's 8 years old, there is a good possibility that the back light is a cold cathode florescent tube. It could be the tube or invertor is going out.
