Slow startup 15 min to start

slow 15 min start up
I have
Dell Dimension 8400
Microsoft Windows XP service pack 3
2 GB of Ram

My computer start time got slow after I updated windows update last week.

I have tried every thing:

Defregmented
Deleted all tmp files
reduced start up programs

I have two printers, one is Epson Stylus C60 plug in to computer at USB port and the other one is Brother 490 which is wireless (Scanner, printer, copy).
Logitech webcam

done a scan with Malwarebytes and/or SUPERAntiSpyware= yes just scan and here is a log from
Ran a scan with HijackThis, then copy-and-paste that new log here.

This is a total time to turn off and turn on computer and open Internet explorer.

It stays on the WELL COME banner for 2 min. before loading the desk top.

I will try the systems restore to night when I will have some time. In past I have spent lots of time with systems restore but never work on this computer. I may load GO BACK from Norton on this computer after all the problem of slow start resolve.

One more thing, I have MAGIC JACK hooked up to this computer, do you think that may be the problem.

I have tried turning on computer without MAGIC JACK but still the start up time is long 8 to 9 min.

Tried booting in Safe Mode
Safe mode does not work at all (tried safe with network also, did not work)
It starts with following:
multi(0)disk(0)Rdisk(0)partition(2)windows\systems 32\drivers

It keep changing through various drivers and finaly freezes. I waited for 10 min but nothing happend so I manually turn of the computer.

Ran chkdsk but could not see the result as it flashes over and gone.

The problem is in loading operating systems:

IT TAKES 1.5 MIN TO START UP WINDOWS
ONE MIN OF BLANK SCREEN
2 MIN OF WELCOM SCREEN
1 MIN LOADING YOUR PERSONAL DATA
THEN
DESK TOP COMES AND START LADING START UP PROGRAMS
IT TAKE BETWEEN 2 TO 3 MIN BEFORE I CAN OPEN UP INTERNET EXPLORER

Only 3 items check in startup

#1.
C rogram files/ Nortonsystems works
#2
C:/program files Norton systemswork basic
#3
C:\ windows\systems32\ctfmon.exe
