Re: There is something wrong with my laptop
Before you click "ok" to acknowledge that you have read the message and its fine to block that remote computer to access your laptop, see if there is a checkbox to say "do not warn me again" on this thing. As a general rule, no remote computer shoud be allowed to access your computer except in very limited instances (some peer to peer networks require it, remote technical assistance etc).
If some legit and necessary internet service requires remote access to your machine, it will ask you in a better format. Point being, your AV software (or firewall) should not bug you about stopping someone from accessing your computer. It should be smart enough to stop the threat, without popping up the message every now and then.
Re: your main issue, since your laptop is a Toshiba, and this is likely a hardware problem, you can go to their website for local repair center. In Jakarta, here is the number: 62-21-634-7108/09/10.
