Replacing 230v PSU with a new 220v PSU

Specs: Windows 7
What will happen if i will replace my 230v PSU w/ a new 220v PSU ?

I have a Intel Core2 - Duo CPU and 946GZ Intel Motherboard.

My pc happened to auto shutdown every time. sometimes like after a minute of starting up it will shutdown. But there are times that it stays for an hour and then shutdown. No shutdown screen, just a black screen and no power on my system unit.

Not exactly sure if you really need the new power supply, though it could very possibly be the cause. Look into your BIOS set up and see of the voltages reported are withing 5% of their nominal values (5V= 5Volts +/- 5%, etc.). If it is not, then definitely replace it.
AS far as the voltages, the voltage out of your wall is nominally 220Volts regardless what the power supply is marked. One company chose to mark their product that it would function up to a maximum of 230 Volts while the other company decided to report that their power supply was intended to operate at the nominal voltage of 220Volts as opposed to North America's 120/110Volts. Either the 220V or the 230V will work the same for you. It is more important to get a quality product with the same ratings or higher than your original. Look for power supplies that are:
A quality name brand
Has 80% certified efficiency rating or better.
Has active PFC.
Has a single 12 Volt rail rather than multiple ones.
Has enough power to run your system and margin to spare for upgrades like a better video card.
Look at Amperage, particularly on the 12 Volt rail since this can be more important than overall wattage in powering high draw components than overall wattage (which can be faked by pushing up the amperage on the 5V & 3.3V rails since this is easier, cheaper, but useless to you).
Has high consumer recommendations on online sites.

Check your CPU temp.

What exactly do you mean here? "230v PSU w/ a new 220v PSU "

Do you mean a 230 WATT or do you really mean 230 VAC?

Hang up and live.

Jefro:
I think the op is taking about european voltages. some in the US have 110/220 switches and others have 115/230 switches (input voltages).

So that leads us to question if the are potentially interchangeable. They have to be correct for the region, but I agree that most are world common but not all.

Hang up and live.

Then essentially purchasing it locally would be best, followed by verifying suitability from the vendor or manufacturer.
Though I was under the impression that the world is basically 220Volt or 110Volt. If you look for international converters they are 110 to 220 or 220 to 110 with assorted adapters for different plug standards. (I had to order one for my daughter's trip to Israel and it came with certain adapters standard, listed by country and others were order-able as optional items.)
