How do I find out what driver/application is loaded at a certain memory address?

Thanks maze-uk, but can you give me more info on this DEBUG command and how it will help me locate the process/driver/app that is loaded at specific memory address? The help for the DEBUG command is as follows:
Runs Debug, a program testing and editing tool.

DEBUG [[drive:][path]filename [testfile-parameters]]

  [drive:][path]filename  Specifies the file you want to test.
  testfile-parameters     Specifies command-line information required by
                          the file you want to test.

After Debug starts, type ? to display a list of debugging commands.

Thank you maze-uk, I can now view the contents of the memory at an address (I was able to do this with a similar tool windbg) but I still cannot see what driver or application is loaded into that memory address. Do you know how I might be able to do this using DEBUG or another tool?

Here'a a Microsoft KB article about Stop 0x0A errors: http://support.microsoft.com/kb/314063

Thanks Callandor, I have seen that KB article already, it was very useful in describing what the 4 parameters mean, hence me asking this question.

You may be unsuccessful trying to find out what soft is the source.
As I told you we had a 'bad serie' of hardware. Once (all) our laptop's motherboard where replace, everything came fine.

Browse the Net (google is your friend) to look for other people with similar hardware  (make/model), who alos have the issue. (and possible solution...)
Also try the support from your hardware manufacturer. They may be aware of an issue and may replace the faulty hardware. Don't wait so you can benefit of the manufacturer's warranty...

I said 'may be'... you may also prove me wrong... :-)
