Mainboard

If someone faced problems like PC shut off by itself, time clock and date were incorrect even after adjusted few times. They were most likely because of mainboard faulty.

If the problem is like cannot boot-up and no screen at all (but power can on), it may because of the following reasons:
-Mainboard spoiled.
- Monitor/LCD spoiled (or may be VGA cable)(provided power is on.)
- Power supply faulty (or 24-pin power supply cord may need to adjust/plug in to mainboard correctly.)

If the problem is no power, then need to check the followings:
- power cord (change it to troubleshoot)
- power point (power source e.g. from wall outlet) (change/plug to another working power point to troubleshoot.)
- power supply spoiled (change it to troubleshoot.)
- power switch of PC's casing faulty (plug the "power switch" power cable to "reset" pin on mainboard to troubleshoot)(this need technical skill.)
(provided that the PC has been switch on successfully before.)
