Hi, I am new to this site, so hi to everyone. Actually i have a problem with dell inspiron 530s. Actually pc was running fine and i tried to adjust the network card antenna and accidently network card plugged out from the socket. I shut down pc and try to adjust it and this is not the first time it happened i did it before and never had a problem. After adjusting network card when i tried to turn on my pc it started continou on and off state. I can't even see initial logo and POST process. I googled it and find some solutions. I unplugged all parts except 2 wires going from power supply to motherboard. One is 12 pin and the second is 4 pin. I did check my ram one by one but no avail. I sent my desktop to my friend and he checked the power supply and said its OK. My friend tried to figure it out and he changed the processor but when he changed the processor computer showed the initial screen but than it again started same on and off process. Now what he says is this is the problem with processor not motherboard. But i am not sure if this could be a problem with processor because it was the last thing i was thinking to change. I need help to figure out what might causing this problem and is it really possible that processor is causing trouble? Please help. Thanks in advance.
