I know that WinNT is 32-bit O/S while Core2duo is 64 bit.

Q1: Is there anyway to speed-up the computerby replacing with the latest computer or modifying the processor or whatever ?

WinNT should install fine on Core 2 Duo. There must be some other reason that the installation failed. Perhaps you could review the failure messages in more detail to see exactly what the problem is.

Virtualization could become part of your solution, of course. After installing a hypervisor (VMM), you could create a WinNT guest (VM) to run on it. Running legacy operating systems and software environments is among thekeyuse casesmotivatingvirtualization.

WinNT should install fine on Core 2 Duo.

Unfortunately because of a problem in NT 4 by default it doesn't. Try finding a BIOS option to limit CPUID max value to 3. Pre-SP6 NT 4 had problems if maximum CPUID value returned by CPUID leaf 0 exceeded 3.
See this for more info on this and other problems in the NT 4 CPUID code:
