One of my PC Refused to start. It has ASUS p4v533-mx Mother board with p4 processor. I have used different SMPS, RAM and cabinet (for the power switches etc...) for testing but it still wont start. It wont even go to POST. Even the Fan is not starting. The indicator on the Mother board light up but noting happens after that. I have even tried pressing f and j continously before powering on the syste. Have even cleared the CMOS but no help. Can someone tell me what may be the main reason. I dont have any other p4 processor for testing it. is there anyway to know where the problem is?
