Multiple errors with booting/closing apps

I've got a new PC recently, pretty decent specs. I would check them, but for the moment, I can't, as I have no access to the paperwork and the system refuses to boot for the most part.
I have no idea what the problem is, but it usually begins to refuse to boot after closing a full screen application (after which it will freeze, and I will have to restart. When restarting, it will occasionally ask me whether I want to run in safe mode, regular, or with previous working settings. I've chosen all three at points.
When booting in safe, it will give a run down of the various .sys driver files loading, but will freeze at TDI.SYS, and will stay like that until I manually power down.
In normal and prev., it will carry on loading at the Windows XP blue scrolling bar bit forever, up to about 8 hours before I've decided to shut it down.

I'll browse around for more system information, but until then, help would be appreciated.

 

Hi, ChrisDigby. Welcome to Windows BBS!

After you manage to successfully boot into Windows, perhaps Event Viewer will provide clues.

Instructions About How to Access and Use "Event Viewer ":

• Click Start.
• Right-click My Computer.
• Select "Manage" to open the "Computer Management" window.
  (Event Viewer will be displayed under the "System Tools" directory item.)
• Expand "Event Viewer" and then select "Application ", "Security ", and "System" to view the logs.
• Look for "error" events that occurred around the time your problem occurred. These events will be displayed as icons with either a white X on red background or a black exclamation point on yellow background. In the security section of Event Viewer, events of possible concern are ones that display a padlock icon instead of a key icon.
• Double-click on an individual event to open the "Event Properties" window which shows details about the event.
  • You can use the up/down arrow buttons in the "Event Properties" window to move your focus to other events in the list.
  • Use the button below the up/down arrows to copy the details for an event to your clipboard for pasting elsewhere.
  • Click on the "http://go.microsoft.com/fwlink/events.asp" link in the "Event Properties" window to view more information from Microsoft about the event.

Alternatively, Event Viewer may be accessed as follows.

• Click Start > Run...
• Type [FONT= "Courier New"][SIZE= "3"]eventvwr.msc[/SIZE][/FONT] in the "Open:" field.
• Click the OK button.
