Have you recently opened the case for any reason? I had exactly these
symptoms recently and eventually found it was due to my having displaced
the data cables to the hard drives slightly. It was particularly
difficult to diagnose because I had just upgraded my CPU with an
Upgradeware adapter and naturally assumed at first that the trouble
was there. I even replaced the PSU, thinking it might be that, but the
roblem persisted at intervals. It finally disappeared after I unplugged
all the data cables and put them back.
