P.S been getting random PC lockups with no BSOD "running vista premuim 32bit" always when playing games. they freeze with sound loops or crackling, keyboard shuts down forcing me to reset
It does sound like your PSU is starving your system of power.
My guess is that the extra power draw during gaming is above what your cheap PSU is capable of delivering.
I would recommend upgrading to a 500w+ Corsair, Seasonic, PCP&C or Antec Earthwatts PSU.

Well i took out my Creative XtremeGamer and things have speeded up "before shutdown took 5 min and i mean 5min" so it leaves 2 things soundcard is knackered or PSU wasn't strong enough
Graphics card make recommends a minimum of 25A per rail for run properly so in other words i have just answered my own question.
iCute 500W is not powerfull enough run my setup
