Hrmm I don't have a windows box to test with so hopeully i can do this by memory, so if the following steps don't work please let me know what errored out.
The following steps should help me diagnose what is eating up all your cpu cycles/ram, from that I can hopefully find a solution:
- Download pstools from here http://download.sysinternals.com/Files/PsTools.zip
- Extract pstools and move pslist.exe into c:\
- Open up a command prompt (Start > Run > type cmd)
- Navigate to c:\ by entering cd\
- Now we want to dump a list of processes and such so I can see what is slowing your computer down, enter: pslist.exe -d -m -x -t > process.log
- After that open up the file c:\process.log in notepad/wordpad and copy & paste it to the forum
