Guys, its really my psu issue. I have bought a spare psu and test. it work. seems that it's my psu causing the problem and long term issue. one side question.. during a year using my desktop.. i have encounter power trips due to lightning of bad weather. can it cause damage to my pc?
Then each time i call it a day, i need to off my plug to prevent wastage of electricity. Then how do i safety off my power supply each time i call it a day?
If ur psu is good, it will prevent dmg to other components.
