Stop Error Screen?

Ok, I'm getting this error message so frequently now I have to seek help on it. Basically, everytime I use BitTorrent or Limewire (it's probably affecting others, but for now that's all I've noticed) I get a blue "Stop Error Screen" that says this:

"A problem has been detectedand windows has been shut down to prevent damage
to your computer.

If this is the first time you've seen this stop error screen,
restart your computer. If this screen appears again, follow
these steps:

Check to be sure you haveadequate disk space. If a driver is
identified in the stop message, disable the drive or check
with the manufacturer for driver updates. Try changing video
adapters.

Check wit your hardware vendorfor any BIOS updates, disable
BIOS memory options such as caching or shadowing. If you need
to use safe mode to remove or disable components, restart your
computer, press F8 to select Advanced startup options, and then
select Safe Mode.

Technical information:

*** STOP: 0x0000007E (oxC0000005, 0xFF542D8D, 0XD8AACBF4, 0XF8AAC8F0)

Beginning dump of physical memory
Dumping physical memory to disk: 18 (goes from 0-100 I think)"

I don't know what's happening and I'm worried something it's dumping important stuff (not exactly a computer wizz and I don't understand all this gibberish), please help me. Email me if you can and prefer.

Thanks in advance.
