Hello all, i dont have a huge background in computers, but i'm learning a whole lot really fast with this computer...
I just replaced my faulty power supply with a logysis acryllic 550w power supply. If i just have the 20 pin mobo connector attached, computer will power up and stay powered up. Altho none of the accessories work: monitor, keyboard or mouse. However, when i plug in the 4pin atx plug, the computer will only stay powered up for about 10-15 seconds before shutting down. I unplugged all my usb components and monitor and it still shuts off. I tested the 4pin atx plug for power and have 12.05vdc at each.
Here is the specs of the computer.
Factory built hp maybe 4 years old.
Amd phenom x4
9650 quad core processor
7g system memory
Nvidia geforce 6150 se graphic card
