How I got rid of the BSOD in windows 7, don't know if this will work in xp or vista.

!!!Use this at your own risk!!! !!!Be sure to create a system restore point!!!

First, remove any program that emulates drives (daemon tools, virtual cd,..)
and maybe even WinRar or 7zip,.... reboot pc and hope for the best!

If your pc automaticly restarts, follow this step, if you have seen a BSOD,
you can continue further on.

First you have to make windows print a BSOD to find out the error later on.
Go to control panel, system, advanced, startup and recovery. Under system failure
check first tickbox, uncheck automaticly restart and choose kernel memory dump.
Now if you get an error, you will get a BSOD wich will tell you
(*at this point, only if lucky* a filename and) an error code (0x 8 digits).
I got 0x00000050, PAGE_FAULT_IN_NONPAGED_AREA without a filename,
the pc crashed but didn't know why. If you do see a filename in the BSOD,
google that name and remove the owning program. Reboot and hope. If not...

You could use 'whocrashed' to scan your dump file, mine only said something wrong with kernel,
being none the wiser I had to search further. You might be luckier.

Next step is to make the pc crash on purpose. Click Start and fill in verifier in the search box,
select driver verifier manager with the blue checkmark in the icon.
Choose create custom settings, next, select individual settings from a list,
next, select all but low resource, next, select driver names from list, next,
select all that is not from microsoft (clicking on provider sorts them by name) and finish.
This will restart your computer and check those drivers for errors on startup.
Your pc will crash while the desktop is showing up, but this time you will see a
file name in the BSOD.
Restart pc in safe mode with networking, research the file that crashed your pc
and remove the program that owns that file. Restart and your pc should be BSOD free!

I had an error with dtsoftbus01.sys, that file name showed up on top in the BSOD,
linked it to daemon tools, uninstalled that and been BSOD free for over 24hrs now
(even installed it again).

If anything fails, restore your pc to the restore point you created.

Hope this helps.
