Service control manager error

I have this error in Event Viewer “The following boot-start or system-start driver(s) failed to load:qic157” after I reinstall service pack 6. I reinstall service pack because the Server applet had error “”Could not start the Server service on \\LIWEN. Error 1130: Not enough server storage is available to process this command.” The second error is gone after I reinstall SP6, How can I solve the second error?
