Hi folks 
I hope someone here can shed some light on this....
I built my system Few years ago, (Win7) see Sig below.
Ever since I have put up with this problem by turnning off UAC.
But I would prefere to have it working.
I have treid everything I can think of,
fresh installs, (with & without extra software)
All sorts of scans, (MS self scans, Eset, Malwarebytes)
driver updates
Updated bios (many diff configs)
With & without GFX card (treid with onboard GFX)
Even downloaded win7 SP1 ISO from digital river and tried fresh install.
!! I give up !! Please help
I feel like ditching all this hardware and starting again, but fear it would still happen.
Article ID: (KB2715460) from MS site, (not sure I can put a link)
The elevated “Check Disk” dialog box may stop responding for a short period of time on UAC enabled systems.
Trouble is it seems to effect more than just the check disk, Like opening some programs, It just makes the system seem very buggy overall, when UAC is enabled "on any level" of the slider.
Thanks for reading, sorry its a bit long
