Specs: Window 7, i7/8gb
Hello, hoping someone can help. Here's my problem.
I was using my computer amid a game and then the graphic got distorted and the screen goes black. I turn the laptop off and tried to restart. The laptop turns on and seems like it's running normally, but there's nothing on the monitor. The screen is just black.
Here's what I tried so far:
1. Unplug and removed battery. Holding the on button for 30 seconds. Plug charger back and tried to turn back on but the same thing happen. Laptop turns on, but no display.

2. Opened the laptop up see if something got loose (ram, harddrive, connector to the monitor) but things seems fine.

If someone can think of what's wrong or what I can do to test what is wrong leave a comment! Thanks!
I plan to try connecting an external monitor, but will need to purchase hdmi to dvi cable first.

Sometimes the cable between the screen and the motherboard wears out at the hinge. When it has been on a while gently lower the lid until it is nearly closed. If at any time you see something then the cable is a likely culprit or maybe the connectors at either end.

Trying an external monitor is the right move.

Always pop back and let us know the outcome - thanks

I think I figured out what's wrong. CPU broke, according to blinking code. Will check back if not,

The fault description make me think the display module (chip on motherboard) is more likely than the CPU (processor). Let us know how you get on.

Did you hear beeps?
And also it varies according to manufacturer. As you said you have a distorted screen may be the graphic card is the culprit.. any how until you check out with the external one we did not get into conclusion..
As you said cpu fault (the fault tolerance of failing cpu is less than 2%) i think it is not..
