Windows 7: Resume from standby/sleep failure, Win7 x64

Weird problem has started happening out of the blue on my Windows 7 box. Been working fine for a few years, now all of a sudden it has stopped resuming properly from standby.

First it starts up but the screen shows nothing - it will stay like this for hours if you let it. So I have to do a hard-shutdown. When it restarts it says 'RESUMING WINDOWS' - despite hibernation being disabled. It then kind of manages to boot but programs etc. fail to load properly so I have to do a full restart. It proceeds to do a chkdsk on C: which fixes several new errors every time like:

"deleting corrupt attribute record (128, "") from file record xxx
0 bad file records processed
57 reparse records processed
(indexes)
Deleting index entry xxxx
complete`

Everything is then fine unless ... you do another 'standby'.

Done a bit of reading / searching around but not found anything that helps yet.



Things I have tried already:

• System restore to before the problem started happening
• Full Windows 7 'upgrade' repair
• Updated NVIDIA graphics drivers

One twist to the story is that when I checked power options I found hibernation disabled AND greyed out. When I try to re-enable it using the command line "powercfg / hibernate on" it gives me this error:

The system could not create the hibernation file. The specific error code is 0xc0000043

Any help you can give would be much appreciated as I really want to avoid having to do a fresh Windows install - I have tons of audio apps installed that all need authenticating etc. and it's a real hassle.

Ok well I think I've answered my own question after all that. For reference - install all latest MOBO drivers folks, think my Win install was using generics.
