Three weeks ago this new issue showed up overnight in my Vista x64 PC.
Putting my PC into standby would cause a sudden restart (reboot) with no
error message/BSOD.
Just the black and white Vista text menu giving me startup choices (Safe,
etc...) because the system had not been shutdown properly.
What changes had I done three weeks ago?
I had switched from NVidia 8800GT to ATI 8450, and updated RAID drivers for
the jmicron controller in the mainboard.
Blame the raid driver, go back to the older one. No joy.
Blame 5% overclocking the ATI 8450 memory, eliminate overclock. No joy.
Hmmm... this ain't gonna be easy, I thought.
Aha! I had set in BIOS the Atlhon x2 6000+ CPU multiplier to x15 (the
correct one) instead of AUTO because it was lowered to x10 when resuming from
standby. Restored the CPU multiplier to AUTO, tested some standby states. No
problem.
Wait one day, test standby again, computer restart!, standby was not fixed.
Check performance monitor of Vista, yellow warning about AMD SATA driver
might prevent resuming from standby.
Would it be related also to going to standby? Changed driver to vanilla
Microsoft driver, reboot, test standby, no joy.
All these failures led me to think again about the ATI 8450.
It had the latest WHQL official ATI drivers... it was not overclocked... and
suddenly I remembered that little "incident" I had when installing it.
I had not moved my PC from under the desk when installing the card and had
worked in a very uncomfortable position and dark environment (the freaking
flashlight was almost out of batteries).
The card was placed, screwed but instead of having fit inside the mobo PCIe
connector it was leaning by its side.
Having not noticed that disconnection I turned on my pc which, of course,
made a handful of beeps and no signal in the monitor.
I switched the pc off, saw the issue, put the card in place and there wit
was my pc, alive again.
Would it be possible that that faulty boot might have screwed up something
in BIOS settings three weeks ago?
That has to be it!
Restarted my pc, pressed DEL and went to BIOS setup.
Loaded a profile that I had already stored in my BIOS with a known good set
of parameters, saved and restarted.
So far I have been able to enter into standby 10 times with no restarts!
Hope this info will be useful to others.
