Hi I was wondering if anyone can help me. Recently I downloaded a program called Defragmenter Pro (trial version) and installed it. Then i ran it, and chose the program to defrag my boot drive and restart after it has finished. So the computer restarted and started to defragment the C drive, and after it had finished, a message immeadiately popped about SCANREGW.exe saying "could not allocate memory for environmental block." Then a whole bunch of other messages saying "There is not enough memory to start SHELL.32.DLL" and "There is not enough memory to start PNCRT.DLL" and others. Then on my desktop I click on any programit immeaditely says there is not enough memory to run it and close other programs and try again. Nothing is working on my computer not even "My Computer" "Control Panel" it just says there is not enough memory to run it. Please can someone help me.

Boot up in safe mode and uninstall Defragmentor Pro. If that doesn't work, Boot up into dos and type scanreg /restore Restore the Registry to a day before this problem started.
