I have a 2 year old dell, wanted to see what socket the cpu was b/c I was wanting to upgrade it. I unpluged all power connectors, took PSU out, took heatsink off, and got the number. Put the heatsink back on, PSU back in, plugged the power connectors, mobo, CD, and HDD, back into place. Once I had eveything hooked back up, I plugged all the cords to the back, mon,mouse,keyboard,etc. Set the case back up, press the on button, but nothing happended.
The lights on the back are working, so is the light on the Mobo.
What do I need to do to find out why it wont turn back on? Any thoughts?
I am not an expert, but do know a good bit about this stuff.
Couldn't find the program to locate socket number. I didnt take out the ram, and the video is built in. What kind of thermal grease, and how do I apply it?
I did reconnect both the 20, and 4 pin. the fan, hdd, cd rom-only 1, and on switch. Everything is connected the way it should. It has got to be something wiht the cpu.
My cpu is P4 2.6ghz. Not that special, expecially for gaming. Thats why I wanted to upgrade it.
This might seem like a stupid response, but usually it is the simplest of things that screw up a reassembly.
1) Did you make sure that when you put everything back together, the power switch connector for the MB was in place?
2) Did you make sure that both power supply plugs for the MB are connected correctly?
3) Did it not work at all? or did it turn on, and then off shortly after - if so, seating the heatsink and fan correctly can avoid overheating that can cause quick shutoff.
Just some quick ideas. Maybe you have already thought of them.
Heck, by the time I posted this, you already answered some of it.
It seems odd that you cannot even get your PC to POST.
You should be able to turn it on even with the HD disconnected.
Yep, everything is back together. I did not take any hardware out, just the heatsink and PSu. Unplugged the Mobo pins, main fan, and everything else that went with the PSU. The power switch is plugged in, but I think that is the reason, because when I first pulled it out, I dont know why, it made a funny sound.
Is this the same PSU or a new one that you just installed?
If it is a new PSU, give the old one a try again (you dont need to install it, but have it nearby the board.) If it is a new PSU, there is a possibility of an error with the PSU, or maybe a bad wire.
If it is the same PSU as before, it is unlikely that it all of a sudden failed.

It does not turn on at all. Not even a second.
Do you mean the Power Switch header on the mobo? You can try bypassing the switch by connecting the pins with the tip of a screwdriver.
Was this power switch connection broken when you removed the connector? It should have 2 metal posts that are sticking up from the MB. Usually these are very close to the connections for the HD LED, POWER RESET.
That is not the connector to the power button. I am referring to the conection with the wire that leads to the power button on the front of the case. This wire is extremely small.
Make sure you didn't forget to plug in the 4-pin power connector on your motherboard.
Exit!
