System stalls in normal mode & safe mode when "Loading your personal settings"

Aloha,
Our problem has been going on for several days now...as I said in the thread title, my 'puter seems to stall in both normal mode and safe mode at the screen "Windows is loading your personal settings".
I've tried six different times this a.m. to boot up, 3 times normal mode, 3 times safe mode. If I can't boot up in Safe Mode I'm lost as to how to start any kind of repair or even system restore.
The system is a Dell dimension 4600 with 512 RAM, dual HD & WXP-SP2. The only users are my wife and myself. I have not assigned a password to the Admisistrator account and we use a common logon screen with no password for ease of use. We do have Guest Account enabled.
Our Firewall and Anti-virus protection is Zone Alarm. Our maintenance routine is to run the following: 1) daily, Spybot S & D, AdAwareSE, A-squared, Window Washer, 2) weekly, Registry Mechanic, 3) monthly, Win Disk defrag and Win Disk cleanup.
Recently, I was in Spybot system tools and opened startup and found a file titled hblogon. I did a google search and found this to be a trojan. My wife followed explicit instructions for its removal and was succesful as far as she knows.
Now in all this info if you've lost track of what my question is...How do I get into the system to boot up without entry via safe mode??? I have not been able to follow your explanations about entering boot.ini in other threads.
I anxiously await someones reply.
Aloha and Mahalo nui loa ( goodbye and thank you very much),

aloha Again,
I was finally able to get into the system by continually hitting the enter key after the splash screen appeared. Once in, I followed all the instructions provided in the thread "Malware removal" by "Chaslang". It didn'
t fix my problem but I'm that much closer to determining with your reviiews fof the logs if my machine is acting as someones "bot"
I remain patient for your reply,

Aloha,
If I've followed directions correctly, you should have what you've asked for. I really appreciate your help and look forward to your reply.
Again many thx,
Dandla

 

aloha TimW,
Thanks for your reply...Since receiving your reply, I've tried a repair of XP both through the recovery console and by initiating a repair from the CD-ROM.
Those efforts have at least allowed me to get a logon screen, however its the wrong screen. It comes up as the Administrator logon followed by qan error message that I do not have authority. I simply hit enter and it brings me to my personal settings. I'm at the point now where I believe I should start a complete Re-install.
I thought I had created a XP re-install CD with SP-2 Slipstreamed into it, however when loading it I get an error msg that it can't find the NTldr...so obviously my efforts failed.
I had previously mistakenly omitted some information that may have proved helpful. While using the tools/startup in Spybot Search & destroy, I found a file titled hblogon.exe Upon further investigation, others on the web opined it appeared to be a trojan. We followed the steps for removal provided by spybot. I don't know how to further determine if I got all of it.
Do you have any other sage advice for me before I foolishly undertake any further major effort, i.e. a complete re-installation.
Thanks again for your help and review of the logs.

aloha tim,
yes both via Ccleaner as your site recommends and weekly with Registry Mechanic.

 

Aloha Tim,
I'm beginning to gather all the things I need to do a complete re-installation.
Yes to your question of back-up for the registry cleaning I have done...using both Registry Mechanic and CCleaner. I've located the Registry mechanic back-ups but can't locate CCleaner back-ups. I have 30 Registry Mechanic backups. Do I restore them all or just the last day, and how do I restore them??? Is there a forum thread for uninstalling and re-installation of WinXP???
again many thx for the help,
dandla

 

Aloha Tim,
I finally got squared away...after doing a complete clean re-install. Thanks for all the help. It was a learning experience.
