So I asked MM today "Can u fix this 'puter in the bedroom, it is running so slowly I can't find music etc". He said "Yes", looked on his laptop what the function was called for Windows 7 and asked it to look for "Disk Cleanup". What a difference, I could tell before I even ran a test as the noise was going "disk noise, noise, noise" whereas in the past it was going "Disk noise..... silence....... brief noise........ silence..... silence etc"
But when I put it on last night it went "Silence" for about 4 mins, I thiught "Oh no", but then it suddenly worked again
