Hello! Today when installing my new graphics card and power supply I got a problem, when I started the computer my keyboard/ mouse didn't worked, I tried using a ps2 keyboard but I got the same problem.. I tried checking if the usb ports had current by connecting my celphone and schecking if the cellphone battery was getting some charge but it didn't worked, any solution to this? I'm thinking in buying a pcie usb card, but if there is another solution please tell it to me.

There are actually just 4 options which come to my mind:

• You forgot to connect all power connectors for the mainboard after switching the power supply. You should check this first!

• A cable is damaged. Try another one if there is one (talking about the cables between power supply and mainboard)

• The new power supply is too weak to power everything. Check how much watt it has and how much your components need (I really doubt that this is the reason though)

• You somehow damaged the mainboard while switching the stuff. In that case you either need a new mainboard or you can try the pci usb card solution.

I checked everithing was connected. No cables were damaged, it's a 550 watts psu.. So ill go for the pci card or another mobo.

EDIT: Lol I set jumpers in the wrong place... everyhting is fine now!
