When I select Standby in the usual way the desktop PC closes down telling me it is `Preparing to Standby` and then shutting down. When I revive it by using the keyboard Spacebar about an hour later, as I have done before, the power light goes to solid green (from flashing), the hard drive light comes on and all the usual fan and drive noises occur. However, the screen does not come back (no signal?) and remains blank and the lights on the ADSL modem remain off, additionally there used to be a click from the speakers (presumably as they powered up) this also is missing.
I can only use the `hot restart` button but the PC fires up normally from that.
I ran both CHDSK and sfc /scannow in case it was something there but all appeared fine. I also checked the Power options and my BIOS settings. The BIOS all appear to be those used as default and the Power options are all set at `Never` - `Hibernate` is not checked.
I tried another Standby selection and about five minutes later revived the PC; it worked fine. After a while I then selected Standby again left it for about an hour and attempted to revive it and the original set of faults appeared.
I am running XP Pro SP2 with wired keyboard, mouse and modem, the motherboard is Asus A8n SLI Deluxe with two GeForce 6600 cards in SLI.
I have now exhausted my knowledge of both XP and PCs and really need help. Does anyone have any idea as to what may be causing this problem and what the fix might be?
Thanks in anticipation.
I should have said that I have been unable to find the file `hiberfil.sys` that MS says should be deleted. When doing a search for it the only reference I can get is in `Windows\system32\usmt\sysfiles` which I believe is a Registry file and should not be deleted.
The only other anomaly I have noted was the left hand lamp on the keyboard (the one that illuminates during normal Windows boot) remained on continually even when HDD activity had ceased. Don`t know if this means anything.
