Some system specs and a little background information would help us to help you.

What do you mean by 180v to 230v ?

BTW Hello and welcome to Techspot.

:hotbounce Hey,

I have a,
Intel: p/4 3.0 ghz
M/B: Asrock p4s61
Ram: 512mb
Video card: 128mb
Hard drive: 40 gd

I changed the voltage on the back of the power supply.
 
These PSU-settings are normally limited to 110/115v and 220/240v
If you live in an area where you get 115v out of the wall, and change the PSU to 220v,
the PC would get only half of what it needs, probably won't even boot.
Similarly, if you live in a 220v area and switch the PSU to 115v, the PC gets double and will blow up on you for sure.

So check the wallsocket-voltage (USA=115v, UK/Europe mostly 220v) and set your PSU accordingly, if it has not blown up already.
 
:hotouch: Hey if I have 115v coming out of the wall and I changed the power supply to 230v would I have hurt anything and if I did what. I ask because the computer still want turn on. :(
 
faulty power supply?

Just turn your psu back to 115v and see if it works.

Read RBSs reply to you above.

It's ok to say you're not sure!

Hey man not sure how to help with the safe mode issue...
but your computer not turning on.
You prob need a new Power Supply.
(You can bring your computer to a shop...and they should have a device that you plug the power supply into...it'll tell you how much power it's getting!)

I did this today and mine definately needed to be replaced.
It's really easy to install...
So if you know anything about putting in and taking out hardware...
do it yourself instead of paying them for the 5 minute job.
(you can respond to this if you need help)

ALSO!

I was told by a computer friend, NOT to buy anything under 400 Watts.
(So don't let them try to sell you one)

This is what I bought today...
for the decent price of 67 bucks (tax included)

Extreme Power 500W ATX 12V V2.01
I think the company name is COOLER MASTER

Works like a charm
(Although...I don't buy these often...so maybe a cheaper one would do the same?)

I believe this one isn't the BEST ....but it's far from the worst.
It's a good one.

:)

NOW if it's a mother board problem I have no idea...
but again....ask them to do a check (don't let them charge you for this...it takes two seconds...)
If your power supply is good...
then it must be the mother board!
