Go to Windows Safe mode
We need to run a Check Disk on the drive
How I do this is to go to My Computer
Right Click on C Drive - Properties-Tools-CheckNow-AutomaticallyFix Ticked
Apply OK YES
Restart
Once chkdisk has finished hopefully you will get to Normal mode
If you do, run Defrag fully
Thanks for the replay.
1. The computer restart to normal mode.
2. I've made the check- It displayed the 'check' window and when it was completed - the normal windows screen.
3. defrag c:\.
That's it, accordind to MS
If it didn't work then it was going to be a Ram issue (so you could run a Ram memory test if you like - but they must be run for many hours)
