Answer #2
That sounds like a broken screen.
Answer #3
yes it does, but why is one hard drive working in normal mode and one is not?the one that does not work in normal mode will work in safe mode and I have been using this hard drive for a year.
Answer #4
Could be also corrupted videocard drivers. You should remove them all and reinstall.
Answer #5
I don’t think a Laptop Graphics card can be removed…
It could be either..Faulty graphics card or screen..
Answer #6
You should try to change video drivers. If the problem persists then it should be a faulty video card…
Answer #7
The video “card” may work OK in safe mode because it is only using basic VGA graphics.
But bad in normal mode when it works at high res..
Try an external monitor, if the problem persists then the graphics chip or it’s interface are faulty.
This would need professional attention to repair the fault or replace the motherboard.
If it works all OK with the external monitor, then chances are, it is a faulty screen.
Check the ribbon cable to the screen looks OK and is in tight.
