PC keeps going into Sleep Mode

Hi Experts,

I have an Acer Veriton S661 Desktop PC running Windows 7.

It keeps going into sleep mode when I'm working on it.
Are there some Windows 7 settings or BIOS settings I need to change?

Regards,
Leigh

yes, it is the same as resetting the Bios
you can also update the bios

was this always happening, or just recently?  if so, a system restore can help too

Check the power meter settings.
Also check if there aren't some shortcut keys that are predefined that'll cause the sleep.

Check your PC Power button, make sure they are not pressed unnoticed by any chance.
Some Keyboards come with Sleep Buttons on the top row, if u are working and if u press any of it
In windows 7 : look for Power options in control panel, check the time before computer goes to sleep on staying idol. if the time is very short, a very minute idol time can make ur computer go to sleep.
Cross Check your computer cable connections between CPU and Monitor, Also check the Power cable of your CPU and MOnitor. If they are faulty screen can go blank every now and then..

Maybe a clear CMOS will help? A client had an Acer PC with Windows 7, but when i did shutdown the computer the computer switched off and after 5 seconds it turned on by itself. Then i did a clear CMOS and the pc didn't go on by itself.

Hi Ricky89,

I am not sure what a "clear CMOS" is?
Is it the same as BIOS Restore Factory Settings?

Hi Nobus,

I reset the Bios.

And sadly the PC went to sleep for good!
When I rebooted Windows 7 offered to repair itself.  I said yes.  It said it was unsuccessful.
Attempting to boot into Safe Mode automatically rebooted every time!

I suspect the hard disk is dying - will run WD diagnostics and re-image if it's still OK.
