I dont know what it is and please reply me fast...!

Short answer: yes. Your Core 2 Duo E4500 supports all three. Intel’s spec page for this exact CPU lists Execute Disable Bit (Intel’s name for NX) as “Yes,” and the chip family implements SSE2 (in fact, SSE, SSE2, and SSE3/SSSE3). That satisfies the Windows 8/8.1 requirement for PAE, NX, and SSE2. On 32-bit Windows, when NX/DEP is enabled the OS automatically turns on PAE, so you do not need to toggle PAE separately. (ark.intel.com)

Quick ways to confirm on your machine (no installs):

  • Windows
wmic OS Get DataExecutionPrevention_Available,DataExecutionPrevention_SupportPolicy
systeminfo | findstr /i "DEP"

If you use CoreInfo as suggested, you can also run:

coreinfo -v | findstr /i "sse2 nx pae"

If NX shows disabled, enable it in BIOS; it may appear as NX, XD, Execute Disable, or Data Execution Prevention, as hinted. (learn.microsoft.com)

  • Linux
grep -E ' (pae|nx|sse2) ' /proc/cpuinfo

Notes:

  • Intel’s page for the E4500 shows “Execute Disable Bit: Yes” (that is NX). (ark.intel.com)
  • Microsoft confirms Windows 8/8.1 requires PAE, NX, and SSE2, and that 32-bit hardware DEP uses PAE automatically. (support.microsoft.com)
  • Public CPU databases and validation dumps list SSE2 for the E4500, which aligns with Core 2’s instruction set. (techpowerup.com)

That should give you both the definitive answer and a quick way to verify on the box you have.

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.
