    reconnect hdd, fdd, pci devices one by one before on your pc

    you must shutdown your pc before connect peripharel devices.

No power from transformer


If the switch mode power supply does not power up then it maybe be faulty.
First check the power button wires from the front panel to the motherboard is seated correctly on the motherboard.
If it still does not boot up then replace the switch mode power supply, make sure the new switch mode power supply has the same or higher wattage rating.

Normally the front panel on/off power button and the front panel reset button plug into connector pins on your motherboard.

If you can find a User Manual for your motherboard it will show you exactly where the switch leads plug in on the motherboard. The motherboard's manufacturer and model number will be printed on the board somewhere.


Good luck.

My P4 VMM 1.0 with win 98 and XP always restart after shuting down. Please help me to solve the problem


This is most commonly an issue of either the ACPI instruction being sent to an ATX power supply being misinterpreted as a restart command, or the controller in the power supply being faulty in general.

The root of the issue can be either your motherboard, or your power supply itself. To test this, try using a different power supply on the motherboard. If it works fine, try testing your power supply on another motherboard. If your power supply works fine there as well, then there's simply an incompatibility of some sort between the motherboard and PSU.

If on the other hand it doesn't work fine on the other motherboard as well, then you know the PSU is faulty.

The degree of fault in the PSU can be anything between harmless and severe; for safety's sake, I would recommend replacing the PSU entirely if a new/different PSU resolves the issue, as your PSU burning out may cause damage to your motherboard and/or (other) connected devices.

I think that you have a faulty power switch there. I know it is new but there could still be a fault. Suggest try a new power switch as for the earthing check that the motherboard screws are all in place and secured to the case.

follow the power cable from the PSU to the motherboard and see if the 21 connection has melted to the motherboard. You are better getting a 500W silent type, but it depends on the peripherals you have installed, try www.ebuyer.com for various makes.
