I have windows 7 professional running 64 bit. A very annoying error pops up every five minutes or so. The message varies and can read "logonUI exe No Disk" or "Outlook exe No Disk" or "your favourite app. - No Disk" depending on what I am running at the time. I have looked at many forums and can see that this error occurred in previous Windows flavours. Some answers point to Malware or infected file, others seem to think it's a corrupt install file. I have a fresh install of win 7. My previous OS being XP.
I have reinstalled Win7 and tried repair functions. No luck so far.
