Windows XP Professional will not Startup Normally

Using a HP compaq nc8000. Intel pentium m. Windows XP Professional SP3. 1 GB RAM. Peripherals: Digidesign M-Box 2 Mini, 2 Gigaware passive USB hubs(connected to Motorola Surfboard 5100 cable modem, 1.5TB Iomega external hard drive, 2TB Seagate GoFlex, Akai MPK25 Keyboard Contoller, M-Audio Midisport Uno interface, Gigaware optical mouse).
About 2 days ago, my computer entered into a startup loop. It started normally once, whereupon it told me that due to numerous hardware changes, I needed to re-register Windows, which I did successfully...the computer subsequently restarted and re-entered the same loop. I was able to start normally once more after this, but only in the Guest log-in. Any time I was able to start normally under my Administrator account, I could get to my main screen, then the computer would flash a blue screen and restart. I also reset the computer to multiple restore points.
The only recent software updates were to my Avast! anti-virus, Java, Mozilla Firefox, drivers for the cable modem, and the standard Windows updates.
I disassembled the computer, re-assembled it, and started it minus all peripherals-to no avail. Same problem. Can only use now in Safe Mode, which does not allow me to access my main software which I use for business. The blue screen flashes too quickly for me to analyze the problem. The only part I can glimpse refers to recent hardware or software changes.
Is there anyone who can assist me. I'm more than capable of doing the necessary tasks with proper instruction. Thanks

As you probably know, the blue screen is the result of a system bugcheck, a serious error condition that makes the operating system to write the memory content to a memory dump file (with the .DMP extension) into the \Windows\Minidump folder (and optionally into the Windows "System" log in the Event Viewer) and to halt the execution after displaying the blue screen.
Analyzing the memory dump file usually gives more detailed informations about the reason of the bugcheck.Upload the DMP file from the \Windows\Minidump folder to your Windows Live SkyDrive, make it publicly accessible and post the URL here, so we can analyze it and suggest you a solution to this problem.
Bye.

According to the specifications of this Notebook, the highest volume for the hdd is 80gb, it could be that you have less than 5% free space and it is this that is causing the problems. Try chkdsk /F for the primary drive, you need to reboot and it may take a few minutes to 20 minutes, depending if the hdd is at fault. Any bad sectors reported means a new hard drive is required.

However, it does sound like a software update that is causing the problem, go into Safe Mode Admininstrator and uninstall those 3 latest updates "Avast! anti-virus, Java, Mozilla Firefox". Any trial software that is out of date also uninstall.

Approximately 3 days ago, I was working in a music production program(Ableton Live 8)when my computer froze. The only significant upgrades I have recently made were the normal Automatic updates from Microsoft, a Java update, a Mozilla Firefox update, drivers for the cable modem I am using(Motorola Surfboard 5100), and drivers for an M-Audio Midisport Uno USB/Audio interface. I was able to shut it down and restart normally. I also defragged the hard drive about two weeks ago. Upon logging in, it displayed a message that significant hardware changes had taken place and I needed to re-register Windows-which was done successfully I was able to start normally twice-however, when I logged in on my Administrator account, the computer would restart after about two minutes, or whenever I started using any programs.
After this, I was only able to login using the guest account-which, understandably, has no access to my most valued programs. Upon restarting the computer, I got a BSOD which I was unable to read. The computer then went into a startup loop. I went through the procedure of disabling automatic restart and recieved the subsequent message: kdcom.dll-Address F7B43160 base at F7B42000, Datestamp 4F8F0F42 Technical info:0x0000007E (0xc0000005, 0xF7B43160, 0xF7B8D864, 0xF7BD560).
After much research, I put the computer into Safe Mode with Networking, downloaded a new kdcom.dll file, and placed that into the system32 folder(after renaming the old kdcom.dll file as kdcombackup.dll). I then went into the command prompt and attempted to register the new file with the following command line: regsvr32 kdcom.dll...whereupon I got the message "Invalid access to memory location." Along the way, I removed unneeded programs, used two different restore points, and also used msconfig to perform a Normal Startup to load all device drivers and services. I also removed all peripherals, disassembled the computer(an HP Compaq nc8000)to remove the real-time battery so I could enter the BIOS and/or reset it(but was unable to find it), re-assembled the computer, and repeated the above mentioned steps in Safe Mode.
After a few attempts at this method, I restarted the computer and it functioned properly. However, when I restarted the computer to make sure it was correctly repaired, it returned to the same startup loop-this time returning a Plug and Play error: STOP 0x000000CA (0x0000005, 0x8437E030, 0x00000000, 0x000000000).
Going back into Safe Mode, I tried the same method, this time using: regsvr32/i kdcom.dll to the same results as above. I then used the command line: regsvr32 obdc32.dll, which loaded the library(supposedly), but returned a message of "DLLRegisterServer entry point not found."
As I purchased my notebook as a floor model from a licensed distributor, I do not have the original startup disk, nor any way to obtain it, as the purchase was made maybe three years ago. The computer has never malfunctioned prior to this point. I keep no downloads on the main hard drive except for updates to the main programs that I use. All media and documents are kept on one of two external hard drives, along with any backups.
This is extremely frustrating, as i am not able to get any work accomplished to satisfy my customers. If anyone can provide any guidance or details on solving this issue, it would be greatly appreciated. As you can see from the body of this post, I possess an intermediate level of understanding, so any instruction you can give will not be beyond my means. Thanks

Good afternoon,
Just replying to see if you've had a chance to analyze the minidump file I sent. In the meantime, I ran an antivirus to scan the main and external hard drives. The result was 10 infected files which I then quarantined. However, this did not fix the problem. Please respond when you get a chance.
Thanks
