What I mean is I have an older gpu that I have been using which was a gforce gt 7600 256mb and when I truer using it earlyer the screen stayed black

Oh no. It worked before trying the GTX 550 Ti?

Omg yeah, what is the old CPU? That is, what CPU is the E7500 going to replace once it works?

It should because my pc had a a core duo in it before hand but it was a e4500 I believe

Can you try the E4500 with the 7600 GT to see if that combination still works?

It makes no difference if the pc had a C2 duo in it already. The mb HAS TO SUPPORT the new cpu.

You're probably right because the E4500 is a 65nm CPU and the E7500 is a 45nm CPU. Back in the old days, I had an EVGA 680i SLI motherboard and my first CPU was the E2180. It is a 65nm Pentium Dual Core, but it's practically a Core2 Duo because it's a Conroe chip. I upgraded to the E8400 which is another Core2 Duo, but a 45nm chip. This required me to update my motherboard's BIOS because a Micro Code update was needed in order to support 45nm CPUs.

I put the old CPU back on and the screen turned on so is there any way to get the new one to work?

You'll need to update to the latest BIOS. That's not exactly the same process for every motherboard, so yo can either figure out how to do it yourself (it's actually significantly easier than you might think), or you can tell us the exact model of your computer so that we might be able to figure it out and tell you.

Edit: In light of what AddRAM is saying, what's the model of your computer? Perhaps there's a list of supported CPUs we can find. I'm not going to ask for the model of your motherboard because I can see that you have an HP computer, not a custom computer.
