May have met its end. Yes you can try replacing parts like motherboard but I don't suggest such at that age.
Spend 20 bucks for some USB HDD case so you can get your files out and move on to a new laptop.
just after waking up I took my computer I used it a bit for google research and 2 minutes after, my screen split horizontal lines right and left and my computer shut down.
I tried to turn it on, the lights that its turned on are on but not the one which indicate that the computer is "working". The screen is black and there is no noise when its turned on apart from the fan inside while before there were other noises when I was turning it on.
I took the battery off click on on/off for 1 minute but no effect (for static electricity apparently).
Here are some characteristics :
Intel Core i3-3120M
Intel HD Graphics 4000
Could you help me please ?
