Had that exact thing happen. Delivered a "high end" (486-66) server to a client. They put it in but were complaining of slowness. When you'd go up to it and do a directory list, it was extremely fast. The computer next to it was ok. You'd get downstairs it would be fast, for a minute or two longer, then it would slow down. We'd get upstairs, cancel the screen saver, check the server, all was OK.
I was just a snot nosed kid (so to speak) but I suggested to them it was the screensaver - to which the not-so-snot nosed guys told me it wasn't (and couldn't be).
