Hi there
I have tried using the recovery console to run CHKDSK. This is what I got.
The volume appears to be in good condtion and was not checked.
Use /p if you want to check the volume anyway.
I will look into doing this memtest and let you know the outcome however if you have any more suggestions in the meantime, please let me know.
Many Thanks

I tried to type /p to run the check anyway but it wouldnt do it.
