Computer Help needed. Emergency PC won't power up after installing new memory

Computer Help needed. Please!

The problem is my computer (Dell 4600) will not power up at all after installing new memory.

How we go to this point: I tried upgrading my system by installing new memory. I was able to remove the old memory with no issues, but when I tried to install the new memory I had lots of difficulty since there was very little play with the release and lock clips due to the Nvidia video card being so close to the clips. I removed the video card and installed the memory just fine and then placed the video card back.

I powered up the computer (the green light came on), but nothing appeared on my monitor except for no signal (it gives that reading if a monitor is not plugged in or the PC is turned off).

I removed the new memory and placed the old memory back, but I got the same issue of nothing on the monitor on the power up. I checked a couple of connections and then when I tried to power up, the green light did not come on, there was no reaction from the PC nor the monitor.

I placed the new memory back in. I compared the wires coming from the power connect and hard drive to a Dell 2400 for some hints since 2 of the wires coming from the hard drive/power connect area were not plugged to the motherboard, but they were connected on the Del 2400. I was hoping to use the 2400's configuration as a hint to where the wires go even though the mother board on the Dell 2400 is the factory original and the 4600 has the MSI motherboard that was installed a couple of years ago.

The wires with the blue wrapping has a tight leash so there isn't much play where it can go. I noticed after connecting it to a section on the motherboard that the PC light came on, but no reaction on the monitor.

Also, I don't recall if the Nvidia video card (Nvidia GEForce 6600) was connected to the power supply. I don't recall removing it from any connectors going to the power supply when I removed the video card.

I was hoping someone out there knows enough about what connections I missed can help me get this main PC of mine back up and running.

I thank you in advance for any help you can provide.

I wanted to thank everyone for their help. After shining a light, I noticed that the memory wasn't locked in all the way. I have the black cable with the white end plastic thing still not connected to anything.

THE ONLY REMAINING PROBLEM IS THE FRONT USB does not work. So I am making due with the ones on the back.

Dell's are created to take only the ram they specifiy or is installed, adding more or taking some away, or getting a different brand even will mess it up.

did you go into device manager to see if they are disabled.

broken power supply or other defects, such as capacitors that went broke were at a Pentium 4 PC normal.

Get that harddrive straight. Vertical or horizontal. You`re doing it no favours. It will be affecting the PC`s access to read and write. Looks like a bomb detonated in your PC!

In fact, i almost want to go down there and fix that thing now, it hurts my eyes to look at it!

U need to plug the video card into one of the cables coming from the power supply
