My Friends: I am running Windows XP Pro. Something is wrong with my computer because it keeps triggering the following error message on start-up: "csrss.exe application cannot be run in Win32 mode". I run McAffee and AVG antiviruses every day. I tried running Spybot and AdAware, same problem. Any suggestions how I may fix this? Thanks
