The system started up successfully(windows 8) but programmes/ softwares installed refused to open in the desktop environment. when clicked to open, it flickered and went off. The touchpad also didnot respond well.
Check your bios and change it to factory defaults. Turn it off and replace the CPU Thermal paste as per manual if you aren’t competent enough have it done at a computer repair shop. Also have the air intake cleaned of dirt and pet dander/hair. Then try to power it on again since it is now an aged system. ( I have the same model and it runs fine after cleaning and Thermal paste replacement.)
