no disk error message - csrss.exe

[Guest]

When my PC boots, I get a Windows - no disk error message (retry, cancel,
continue - cancel is the only thing that works). Task manager associates it
csrss.exe as the appropriate process. Can you please suggest how I can make
this go away?
Many thanks, Helen Ryle

Helen, the csrss.exe file is located in the folder C:\Windows\System32. In
other cases, csrss.exe is a virus, spyware, trojan or worm! It's a
important core system file. Do a Search for csrss.exe. If it turns up
anywhere other than the System32 folder
delete if you can.
