Hello,
I have SONY VAIO VGN-NS21SF and from time to time I have overheating issues. After this issue, what happens is, that the notebook takes ery long to start. It just stays in the black screen in the beginning and it takes about 5-10 minutes to show the first VAIO screen. After that, when I restart or shut down notebook correctly, it starts normaly and it is not stuck in the black screen, happens only when it shuts down by itself because of overheating.
But last time, it overheats itself and it looks like that it is stuck in the black screen forever. I turn it on and after 30 minutes in black screen, no progress. I tries to open the notebook and clean all the dust, but no progress. My question is, what could be the cause of this?
Thank you. Lukas.
