Hi all.
Hope i can try to explain this problem thats just suddenly started happening with my vista os in the last few days best i can.
A few days ago after having vista run fine for months with all my usual stuff on it like nod32, diskeeper, games etc i decided to do a bit of a clean up as you do periodically with your pc.
With diskeepers boot-time defragmentor i set this to run which basically you can set chkdsk to run before it bootime defragments as per usual.
It re-booted went into doing the usual chkdsk as you can do aswell from right clicking on your hard drives icon in my computer and found that chkdsk found a corrupt file or two and began to repair them.
So i thought ok ill just it do its thing as its been awhile since i ran chkdsk either through diskeeper or the normal way and then found this message started coming up on the chkdsk screen.
"Replacing invalid security id with default security id for file xxxx"..and basically doing this for thousands of files for well over an hour.
So i let it complete and then found on rebooting vista that it gets past the green loading bar then the screen goes blank, does not log into vista at all and im left with just the mouse cursor on the screen and thats it!.
Over the last day and a half i have reformatted about six or seven times and systematically on my normal reformat routein installed a few drivers tried chkdsk to see if any of these cause the problem which then chkdsk runs fine with no errors and then with programs etc and all seems to be fine until i get literally everything installed again, run chkdsk from diskeeper, it finds errors and it does this all over again.
Ive googled about and searched on here and tried to find one or two articles on the net on "what" actually causes it.
Again, i can run chkdsk fine after the first few programs, drivers, windows updates, go on the system fine but again, it seems to just do it after a lot of stuff has been installed and i have done a hd error scan with hdtune aswell and cannot find any hd bad sectors.
Hope any of the above made sense and even any little suggestion would help.
Ive come across some problems before in my years of using a pc but this one tops the lot for me.!
