our cpu is not working at all no power no fan no lights (led). i had the power supply replaced but still the cpu won't work.what would be the problem? but the monitor light if front is blinking but not opening too.
Well assuming that the new PSU is all good then the next port of call is the motherboard. If it is completely toasted then that could explain the total lack of response. I am also assuming the power switch on the PSU is on, the power cable is plugged into a working socket and all leads and connectors are in the right place especially the power on lead to the power on connector on the motherboard.
