when i get to the login scree, my computer shows a message and counts down 1min before it restarts... it says something about NT Authority services.exe code 128 error... i don't really remember.. anyone have any ideas??

This is Micorsoft's solution:
To resolve this issue, follow these steps:

1. Restart the computer in Safe mode:
1. Restart the computer.
2. Press F8 when you receive the "Please select the operating system to start" message.
3. On the Windows Advanced Options menu, use the arrow keys to select Safe Mode, and then press ENTER.
4. If you are running other operating systems on the computer, use the arrow keys to select Microsoft Windows 2000 in the list that is displayed, and then press ENTER.
2. Click Start, click Run, type regedit in the Open box, and then press ENTER.
3. Locate and then click the following registry key:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\lanmanserver\Shares
4. Back up the registry key:
1. On the Registry menu, click Export Registry File.
2. In the File name box, type Shares_RegKey, and then click Save.

This step saves the Shares registry key to the Shares_RegKey text file, which you can use to restore the key in the future. By default, the file is saved in the My Documents folder. For information about how to restore the key, search Regedit Help for the Import Registry Key topic.
5. Examine the list of values in the right pane of Registry Editor.

Notice that the Data column contains the paths to shared folders. For example, you may see a line similar to the following:

CSCFlags=0 MaxUses=4294967295 Path=E:\NS Permissions=0 Remark= Type=0
This refers to the E:\NS shared folder.
6. For each value, use Windows Explorer to make sure that the path displayed in the Data column represents an existing shared folder. Delete all values that do not correspond to shared folders.
7. Quit Registry Editor, and then restart the computer.

thanks for the help... but the thing is... i can't even log in on safemode... i tried it with safemode and networking, never tried just safemode by itself... i'll post up if that still doesn't work.. thanks again!

Just after logging in, with the message being displayed, hith Ctrl+Alt+Del to bring up the task manager. Then click File | New Task, and type in shutdown -a. This will cancel the pending shutdown request, and can be run as many times as needed. Then run the Microsoft fix given, and this should resolve the issue. I would also recommend running Windows Update and scanning your system with any available a/v scanner. At the very least, install this patch: Q823980/MS03-026: Buffer Overrun in RPC Interface May Allow Code Execution
