    • +5 should be +4.75 V to +5.25
    • −5 should be −4.50 V to −5.50
    • +12 should be +11.40 V to +12.60
    • −12 should be −10.80 V to −13.20
    • +3.3 should be +3.135 V to +3.465
    • +5 should be +4.75 V to +5.25


    So your power supply voltages are fine, but the CMOS battery needs changing

    What digital voltmeter did you get?

    thanks again, i just changed the CMOS battery and will re-plug the PSU and try using the computer again.
    is there any other component that is possibly broken ?

    Of course... that is why one tries to figure out what the problem is.

    Did you check for a BIOS update, test the RAM, check for swollen capacitors etc
    as suggested on page 1 a week ago? (and again on page 2)

    - for bios update, i cannot find any update on this bios. but i don't understand how it relates to my issue.
    - for ram test and swollen capacitors, i will check them tomorrow, this is already at night and the room is too dark.

    thanks again.

    Hopefully the new BIOS battery is all it needed.
