I try to start my laptop again to quickly dxdiag it, but the screen wouldn't turn on (while I never turned it on the whole day). I heard the Windows sound again and I tried to login without screen so I typed in my password and after a few seconds I hear the login sound, but I can't see anything so I just turned off. Then I try to turn it on again but the screen was still black so I quickly turned it off and on again and now the TOSHIBA logo came on and my screen worked.
I have a customized animated Windows logo but it was stuck. I came on the login screen and everything was slow and buggy. After a few seconds only a half of my login avatar came on the screen and I was stuck, so I turned it off once again..
Couldn't reach for my specs but the model's name is written under my laptop: it's a SATELITE P300-1FY. I didn't customized it so the standard laptop has the exact same specs.
My screen is fucked up as well now..
Sorry dude, that sounds like there's something wrong with the connector on the monitor or there's something wrong with the mobo.
I would try to take it to the cheapest shop you can find
Post your problem on a site like TomsHardware where there are more experienced people than ourselves at MPGH.
It's a bit more harder for me to go to the repair shop, as I'm still in China. My mom says I have to wait 'till I get back because the shops here fraud you, they take out your good stuff and replace it with shitty materials.
It looks like I'll have to find myself an internet cafe for the 2 weeks..
