I just got all my parts in and put it all together. When i go to power up there is no sign of any power. I don't think its my power supply because it got the sonata III case which comes with a very good PSU. Any tips for what i should do to find the problem?

Check whether the PSU will power on by trying to "jump start" it. If that works, then you can start double checking all of its connections with the motherboard and the motherboard's connection with your case as suggested above.

The polarity of wiring on the power and reset switches doesn't matter, only on the LEDs.

If you have both the 20/24 pin main ATX connector plugged in, AND the 4-Pin ATX12V P4 CPU connector plugged in, then the board should boot fine.
You could test the PSU. Jump start it (on the main atx connector, short the green wire with any black wire, using a paperclip), and see if it stays on. If not, then its probably a faulty PSU. If it works then proceed (though, in rare cases, it may still be the PSU at fault).
Setup everything outside of the case, with the mobo on top of its cardboard box. Plug in only the essentials:
- PSU (namely: main 20/24-pin ATX connector and 4-pin ATX12V P4 CPU Connector)
- CPU w/ HSF
- Single stick of ram
- Videocard if there is no onboard video
- Monitor
- Keyboard
- System speaker/buzzer
* Use a screwdriver if your board doesnt have an onboard power switch. Jump the two power switch leads to turn the power on.
If it won't POST, try different RAM slots. If it still won't POST, pull out the ram (so no ram in the system) and listen for error beeps. If none, pull the vidcard and listen for error beeps. If none, re-seat the CPU/HSF and try again. Report back with results if you're still having issues.
