Constant restart loop

Hello

I've had many devices this christmas for my computer (mostly USB).
I've set them up fine, having no problems.

Then today i plugged in my freecom external DVD RW, installed two programs that come with it - "cineplayer" and "easy media creator"

i then restarted my computer. On reaching the desktop there was about 10-15 seconds before the computer went into reboot. This constant reboot then went onto a loop. Sometimes it rebooted at the welcome screen, sometimes it rebooted after being on the desktop for a couple of seconds. It seemed random.

I tried safe mode: straight into the reboot loop again.

I cleaned for dust inside (thinking overheating of motherboard or something i read somewhere)

then i did a reboot to a "previous working condition" thingy.

The computer started up but with that old error message "your system just recoverd from a serious error". It keeps coming up and up and up all the time.

i uninstalled both bundled software programs from my computer. I havn't uninstalled the dvd driver which was automatically installed. Some help with that would be great.
(i hope i'm in the right section)

i'm obviously a bit worried about this error though now. The "more information" section of the error window goes on to give these numbers:

BCCode: 1000007f BCP1:00000008 BCP2:80042000

would it be good to follow the help here: http://support.microsoft.com/default.aspx?scid=kb;en-us;316434

thanks for any help
