Unexpected Vista placed into a sleep mode, requires to turn PC OFF then power back ON

Hello,

I've been having a problem with Windows Vista x64 that has occued intermittently for the last two or three months.

All of sudden, sometimes when I'm away from the computer the PC is placed into, from what I can determine, a sleep mode.

The monitor is turned OFF but the PC power light is ON. The PC doesn't respond to the keyboard or mouse and a 1/2 press of the power button.

The only method I've been able to get back to Vista is to Power OFF the PC then power back ON again.

I've checked all the power settings including the advance settings and the bios, but haven't yet been able to resolve the problem as it only occurs perhaps from one to three times per month.

I looked in the Event Viewer, however I'm not certain exactly where to look.

Event Viewer: Under Administrative Events there are warning and errors such as

Errors found:

7/26/2017 1:42:45 PM service control management

11/26/2017 1:35:26 TaskScheduler
The previous shutdown at 1:21:41 PM on 11/26/2017 was unexpected

I've also checked all the HID device power management settings disabling any power control of a HID device.

Greyed out " Allow the computer to turn off this device to save power"
Unchecked "Allow this device to wake up this computer"

I also checked the monitor settings and disabled any settings that could potentially put the monitor to sleep or turn it off. (Monitor a Nec V323-2 )

Perhaps it's a hardware related issue? The Thinkcentre PC is nearly 10 years old. I probably need to clean the motherboard, even though it's been vacuumed out motherboards as they age a type of dirt builds up on the mb circuitry that can only be removed by washing the motherboard with some mb cleaning solution then allowed to dry.

Did you ever get this resolved?

It sounds to me like Hibernation mode is enabled. It's possible that it's being activated by a low CMOS battery voltage.

Problem hasn't occurred lately, can't remember the frequency, months perhaps?

I'm kept being told to get rid and Vista and upgrade and I reply as soon as I upgrade my 10 year old PC. I have a Windows 8 upgrade that I purchased for around ~$55.00, but see no reason to upgrade to Windows 8.x on on older PC.

Sure Window Vista sometimes bogs down and become slow, but so would Windows 8 or windows 10 if installed on the same PC.

Well, it depends on how you manage that machine. But even Windows 7 will always be better than Vista, because, if for no other reason, it is 10X better at resource management, meaning the same exact system running Vista is actually more sluggish than the same system running 7.

As for 10, though, that really would depend upon what you do and how much (if any ) you've upgraded. My CPU is 10 years old, my mobo 8, and I built this machine 7 years ago. But I've have since replaced all the HDDs (and added 2 SSDs), plus all the video cards, so it is more than adequate to handle Windows 10 (which I've been running on this machine since the early Technical Preview 2 releases, or, roughly, 3 years now).

I would agree taht Windows 8 would probably feel more sluggish on that machine, perhaps even more so than your current Vista install - but 10 would not be as bad, 10 is to 8 what 7 is to Vista....

Yes, I know I can upgrade to Windows 7, but then cost becomes a factor. My copy of Vista Ultimate is legally licensed and registred with Microsoft.

I see alot of downloads for Windows 7, obtain a license key, etc. but it's all totally illegal.

To legally upgrade from Windows Vista even to Windows 7 is going to cost a few bucks, i.e. to purchase an legal copy of Windows 7 with a license key. I would need to purchase a retail licensed copy of windows 7 with key to upgrade my PC. That money could be spent towards a newer PC running a legally licensed Windows OS such as 7, 8 or 10.

Not necessarily, Albertz. I've lately seen that you can still install Windows 10 using the Product Key you got with Windows 8. You don't even have to install Windows 8, just use the key.

If you have an extra hard drive, I'd remove the one with Vista on it and install Windows 10 on the extra, just in case it doesn't work. All you have to lose is some time ...

I really don't want to install Windows 10 on this old PC ... It's older hardware architecture that's ~10 years old and doesn't really have the system requirements for Windows 8 or Windows 10.

What I need to do is replace the old PC with another PC that has later hardware architecture and either an OEM or retail copy of Windows 10 already installed.
