Hi, Just installed a second hand Mobo with my XP3200 chip and a new 520W trust power supply. I have put in one stick of Ram and video card. When I try to power up the CPU fan comes alive for about 15 secs then the power supply switches off. The Mobo has in addition to the normal power supply the 4 pin 12v ATX connection.
The Mobo is about 3 years old could this modern new power supply be in compatable? Or can anyone suggest anything else. I have tried the Mobo out of the case on a piece of wood and also in the case. I have tried running with just the CPU, fan and power supply.
