On Wednesday when i built my PC the Psu began smoking, I knew this clearly wasnt right so opened the case and pulled it out.

I ordered a new PSU on wednesday evening, it arrived this morning. The New PSU is now fitted BUT the machine wont start. The PSU just seems to hum slightly

it IS plugged in and i am 100% sure the powerswitch is connected to the right place on the motherboard. i have connected the 24V connector to the motherboard from the new PSU and the 12V to the motherboard but nothing seems to happen! again the PSU seems to just hum.

if anyone could inform me of what i am doing wrong PLEASE post. if i need to post pictures to show you then i will.
 
that could be the problem as your M/B probably monitors CPU temp, i'd test the fan and does the hdd spin up, if it doesn't then check the output from the PSU preferably with a volt meter (don't worry, not expensive, only £10) on a molex connector (power)
put the volt meter on red and black (next to each other) it should read 12V then go with the yellow and the other black, it should read 5V
 
Ill try to check that later, my dads an electrical engineer and i KNOW he has one of thoes, ill update tomorrow!
 
What PSU are you using?

Prehaps it's not powerful enough to run your computer

Big B is an expert on PSUs - wait til he's seen this thread before you do anything
 
Thanks for your help, a relative of mine has sorted it out for me.. although i cant really think of anything that he did differently!
 
in all probability the power supply took out other components with it

only way to tell is to test your components individually in a known working system
 
Yeah, right now, test out the other components. A bad PSU may have damaged some or all the parts, but if that's not the case, you could still have an insufficient PSU. Check the PSU link in my signature for an indepth explaination.
