Laptop keeps shutting down after around one hour of use
I have a 2- year old Compaq Presario that keeps shutting down after around one hour of use. Problem started a year ago and keeps on repeating. These are the things I have already done to revive my laptop:
- Cleaned the fan and heat sink.
- Applied thermal paste to the heat sink.
- Reformatted the laptop.
- Installed updated anti-virus and made sure there are no malwares and Trojan.
- Brought my laptop to the service center.
- My laptop would be functioning well for around a week after I tried to fix it but it will start shutting down again. Is there any other way to truly fix it?
