This could explane my problems i'm having. (Thanks)

Could it be that the old PSU had damaged somthing (vidio card, hard drive,)?
I better get my hands on a meter to see if the new PSU is even working right.


I can't see it being undersized since the new one is 550w ATX. (the old one
was 500w)Or did I even hook it up right?
The new one has one 20 pin and two 4 pin connecters for the motherboard.
but I only room for one of the 4 pins. One has two yellow and two black
wires (this is the one I hooked up) and the second 4 pin has Red, black,
ornage and yellow.

Now the motherboard manual says that the 4pin should be two +12v and two
ground.

Is there a way to test the max load with out a meter?
