Ok, so before i started swapping stuff i tried starting it up again, now it wont start up at all the power light comes on and the fans but the screen is black.

And now it beeps 1 second after powering up???

So i swaped the psu with one thats exactly the same from my other pc (both are the same model) by the way the psu is 160w and all the adapters are custom made for the mini-tower. It still dosent work. I tried that psu in the other pc and guess what, its working just fine. (good news i guess since i dont have to go psu hunting)

Ive noticed one thing do, the fan that makes the rev sound when i plug it in, isent the psu fan as i thought, its the cpu fan ( but its working great when i turn the power on). <----im guessing this is related to my problem somehow

Ive checked all the wiring, everything looks good.

Everything is getting power.

Ive tested the ram

Ive tested the video card, ive tried the tv out, ive tried the onboard monitor adapter and ive tried using another videocard (the exact same model).

Ive got nothing else to disconect from the pc since the network card is built in, theres no modem.
