Solved: PSU problem!

i just recieved another psu and installed it, now when i turn on my pc it makes a this sound that sounds like its short-curicuting and then it shuts off. what does that mean?

 

Sounds like you diagnosed it. Did you get smells? Examine mobo and everything connected for evidence of a short. When you find it you've most likely found the problem.

 

Didn't you already have a problem with a power supply? What is the EXACT make and model of the power supply you are trying to use?

 

ok false alarm guys...for now. it seemed that i had the gfx card power plugged to the HDD and DVD/CD drive and vice-versa, hope it didn't do any damage but the HDD and CD DVD drave had some weird things when they tried to start up, it still sounded like they were short circuiting but everything is working fine rom the looks of it, let me just see what happens when i insert a disc to be sure.

EDIT: ok thanks for fast replies guys but i think everything is going good now for now. SOLVED!
