Extremely Slow Boot

I have an HP desktop that's about 2 years old (P4-2.99Ghz). It have 1.5 gb
of memory.

The problem is that it boots EXTREMELY slowly even in SAFE mode.

Once it's running it performs OK.

I've run AV and anti-spyware on the box as well as System Mechanic and
CCLEANER to clean the registry.

I have also defragmented the hard drive.

Is it possible that this is a hardware issue? memory? motherboard? HDD?

If it could be hardware what's the best way to diagnosis the problem?

disable slow boot in BIOS. is your memory clocking up...
