When you typed your post the requirement to "Please read before posting" said;
"If you're asking for technical help, please be sure to include all your system info, including operating system, model number, and any other specifics related to the problem.
Without that and any other relevant information all I could suggest is, take it to a recognised and trustworthy computer repair shop to be fixed.
