My computer's monitor goes into standby right after i push the power button on the pc
Hi everyone, I have an HP pavillion 6330 It was working fine. I tried to put a another motherboard that was used. I used the same HDD, Floppy drive, cd rom, and the same power supply. Then, when i turned on the computer with the used motherboard it didn't work with that motherboard because the computer didn't even start up and it just didn't boot and the monitor started to go into standby. Seeing this problem happen with this motherboard i put the original motherboard of my hp pavillion 6330. Now when i turned on my hp pavillion 6330 the monitor goes into standby mode immediatly after i press the power button on my computer. I don't know if the problem is in the power supply, hard disk or a connection of the cables. If anyone can help me... I would appreciate.
