Game programs and other applications keep crashing with the same error!!

When I am running some programs on my computer, the program crashes and I get the same error report which says "please tell Microsoft" and I have sent it three times. It occurs usually when I play computer games but I also happens when I run other programs as well. Please help!
Error Report: it says the following info on the process will be sent: mm6.exe(or whatever other program crashed), ntdll.dll, kernel32.dll, USER32.dll, GDI.dll, ADVAPI32.dll, RPCRT4.dll, DDRAW.dll, msvcrt.dll, DCIMAN32.dll, mss32.dll, WINMM.dll, smackw32.dll, LPK.dll, USP10.dll, faultrep.dll, VERSION.dll, USERENV.dll, WINSTA.dll, NETAPI32.dll, WTSAPI32.dll, SETUPAPI.dll, SHLWAPI.dll, Apphelp.dll, then says something about a thread which I can't copy for some reason and I'm not typing THAT out!

Thanx in advance.

Here are 3 ways to search your errors:

1. Look in your Event viewer: rt. click My Computer then click Manage then Event Viewer.
Or: Administrative Tools/Event Viewer or Start/Run/ eventvwr
Open the system as well as the application tabs & look for X errors. Click error line for details.
Post back the source & event id especially of errors that seem to coincide with a crash.

2. View your Error Log via:
[1] Start Menu
[2] Help and Support
[3] Pick a Task
[4] Tools
[5] Advanced System Information
[6] View the Error Log

3. Go to start | search (type in) .dmp
Note the location of your latest .dmp file.

Then:

1) Download and install the
Debugging Tools from Microsoft
2) Download and install this
debugwiz
3) Open the Wiz & Browse to, or paste in the path to, your latest .dmp file.
4) After the Wiz creates a Text document attach it back to this thread.
