Hi i need to know that this old Intel Core 2 Duo CPU E4500 @ 2.20GHz can have support for PAE, NX, and SSE2.
I dont know what it is and please reply me fast...!

PAE - Physical Address Extension - this allows your computer in 32-bit mode to access more than 4GB of RAM, although each process is still limited to that.

SSE2 - Here is the Wikipedia article on that: https://en.wikipedia.org/wiki/SSE2

NX - No Execute instruction - helps protect your system from malware.

You can find all of this stuff with simple Google searches. Your processor should be able to handle this, though not sure about NX. Go to the Intel web site and look at the specification pages for this processor.
