Weird things happening after upgrade to v1.9

Question

Before I start, here are my system specs:
875P Neo FIS2R v1.9
P4B 2.4Ghz running stock 533Mhz FSB
2x Kingmax DDR400 running 333Mhz DC
ASUS V8460 GF4Ti4600 128Mb (No Over Clock)
120Gb Seagate SATA 7200.7
Creative SB Audigy
Enermax 431W PSU
Rest not important!
Anyhow, I upgraded to the 1.9 from the 1.8 and for whatever reason, now when I cold start the computer, I get 2 sets of double clicks coming from the PC Speaker and slowing the boot process.  To clarify this some, I push the PrOn button and you will hear 2 clicking like sounds say 1/2 a second apart and then a pause and then it will do it again.  After this, it will finally initialise the video and start posting as normal.  All up, it takes about 5-10 seconds to get over this initial problem.  It also now takes much longer to detect the SATA HDD.  Around 6-7 seconds as oppsed to no delay with the 1.8 bios.
This really hasn't affected the use of the computer but why is it doing this.  The really strange thing about it all is that sometimes it makes these clicking noises and other times it just boots normally.
I cleared the CMOS and reset all the bios settings.  I have since tried a few different settings with very mixed results.  Unfortuantely though, the problem still rears its head every now and then.  I am thinking of reflashing back to v1.8 but I thought I would see if anyone else has experienced this strange behaviour.  
Thanx.

Thanx for your post REILLY875 but this problem I have oocurs the minute you turn on the computer, before it even starts to Power On Self Test.  I can assure it has nothing to do with the loading of Windows drivers etc.
This delay I mentioned occurs from the moment I turn on the computer with the PrOn switch to the time it starts posting.  Once it starts the post procedure, all is then fine and it continues on to boot from the hard drive with no problems.
I made mention of the fact that it now also takes longer for the bios to detect the SATA drive, quite likely a minor fix on MSIs behalf due to some HDDs not spinning up quick enough causing HDD detection and boot problems.  I have read about this.  It could be they deliberatley added a delay to this detection process.  Not quite sure.
But in any case though, whilst this unusual sound I get from the speaker isn't a problem, it is quite strange as you say and is clearly not normal.  The really annoying thing is that it does it sometimes and not others.  I really hate intermittent type problems like this one.
I guess at the end of the day, unless your running a P4EE, what was the point of updating the bios.  I know all us hardcore computer enthusiasts do it because that's just what we do.  It's just a shame it wasn't more fool proof.
Thanx.
