New prossesor won't work, PC lights and fans turn on.

Hi and happy holidays! I recently got my new (slightly used ) AMD Phenom II X4 840 Edition Deneb 3.2 GHz 4x512 KB L2 Cache Socket AM3 95W Quad-Core Processor - Retail HDX840WFGMBOX (Black) from amazon. I installed the processor with no trouble and go to make a test boot and....... WHAT THE! The lights and fans turn on but NOTHING I repeat: NOTHING goes on the screen. It just goes to sleep! (I had the side of the PC case off, for good measure.) Here are some screen-shots from CPU-Z for my current processor info and motherboard:

Did you get the notch on the one corner of the CPU in the correct position with the socket notch ?

Yes, I did. (It is a triangle :) )

When the processor got in, some of the pins on the edge were slightly bent. So I straightened them with a gift card. Does that have something to do with it?

DocBrown said:

If any pins got bent just enough not to fit in their respective holes, that would most likely cause a problem.

The pins did go in fine.

I don't think it is that, that happens to people on occasion

Have you checked all your connections all the hardware make sure everything is plugged in

I know al the connections are fine. I am using the same PC with my Sempron installed.





Could it be a wattage problem?




This also happened when I installed new RAM. It is fixed now, though.

Oh, and the fan that came with the Phenom is SMALLER than the one from the Sempron. Is that a problem?
