Hi,

I just recently built a new computer using some older parts from a different pc. I had everything plugged in but I bought a psu that didn't work. I installed my old psu and the computer turned on (fans were running on case,CPU, and gpu) but nothing was working. I had no display, also the USB ports were not working properly. I would just like to know if anybody has an idea of what's happening or how I can fix it. Thanks :)

I don't know what most of the components are because I got them from different bestbuy computers or from friends computers. The motherboard is asus and the graphics card is an msi r7770 but other than that really no info, sorry.
