Hey dudes, im a newbie to pc building and have built my new system, lemme tell u the story from the start

Basically i ordered a mobo and i scratched it, i dndt realise that this was a problem so i carried on and when i switched it on it dndt work BUT the power light that was on the mobo was on, i reslised i needed to replace the mobo, i have. But when it was scratched cus i was so confused i kept TRYING to fix it, changing this and changing that, i know im a *censored*, cus i kept switching it on and off repitivly in fustration......now i have my new mobo i have put it all together but i get a burning smell eveytime its on? ive CHECKED all the components and they are fine, no marks or smell, am wondering if wiring is faulty? or is it the psu? has that gone bcus of me? anyhelp whould be majorly appriciated!!!
HashWhat are the specifics of the components - everything, including make/model of PSU?

Are you sure it is assembled correctly? Start with just the MB, CPU/FAN, 1 stick RAM and video card.

Some punctuatin MAKES your posts easier to read too. yeh lol my english is amazingly retarded

anyways

P4 940 3.2 D proccesor
Asus P5WD2 Premium mobo
1 gig of crucial value ram
256mb MSI geforce 6600 Graphics
2 x DVD/RW
1 X Floppy drive
600W PSU (No brand)

yeh basically i dnt think its psu now, i switched it on and smoke seemed to be COMING from bottom of the mobo, the side closest to the floor, where are the LED connectrs are, i was wondering? is there a specific way that the LED,PWRSW and all that connectors need to be in?cus ive matched em up how there meant to be according to the manual but i could turn them 180 degrees and theyd STILL be in the same port....if u get what i mean, any ideas? i think that mobo is faulty ?Smoke coming from the component is never a good sign!

If the connectors are in the right spot, rotation is not an issue. I would think about a replacement motherboard and possibly power supply. Be sure and test it with the board out of the case first with just the CPU/Fan, 1 stock RAM and video card only to see if it works BEFORE putting it in the case and hooking in other components. You have to isolate where the problem is. tried it, still smokey, could it be to some of the wires being faulty? like one of my 4-pin fan connectors as a bit bent? could it be that? its really pissin me off cus ive had these computer components for ages and somthin always goes rong
