Blue Screens and "Available Memory less than 15MB" Messages.

Recently (ie over the last five days), my computer has suffered Blue Screens of Death on two separate occasions, with the last one being three days ago. I have also had two separate warning windows pop up, saying "Available memory is less than 15 MB," even though my Computer folder tells me that I still have 528 GB free.

I've tried using Event Viewer to backtrack these events. The last time I recieved the MB message (which was earlier today), Event Viewer logged a "DNS Client Events" warning and an error in the Bonjour Service. As for the last Blue Screen, I THINK it showed a DistributedCom Error (the text reads: The application-specific permission settings do not grant Local Launch permission for the COM Server application with CLSID (LONG STRING OF NUMERALS HERE) and APPID (OTHER STRING OF NUMERALS)* to the user NT/Authority/System SID (BRACKETED NUMERALS)* from address LocalHost.

Now, I am going to flat out admit that I am a complete newbie when it comes to anything other than basic applications, and it wouldn't surprise me if the Event Viewer stuff I posted is completely unrelated to the problems I'm having. Either way, does anyone here have any idea of what might be going on with my computer, and how I can fix it?
