Won't wake from sleep and fans on full - needs to be shutdown

Hi,
problem still occurring, whenever the computer goes to sleep on waking I just get the whirring fans and no action until I press and hold power button to shut down and then start up afresh.

I have it on default balanced power settings but with display set to 15 mins and sleep set to 30.

I did have a look in BIOS to get some more info for you - I don't understand it but it may help;

BIOS Power Management:
ACPI suspend type S3 (STR)
Remote wake up is ON
Auto Power ON is DISABLED
AC Recovery is OFF

Advanced BIOS:
Boot up numlock status is ON

Integrated peripherals:
Onboard LAN boot Rom is DISABLED

these were just bits that jumped out as possibly relevent????

OK guys, this is what I have done altogether;

BIOS power management:

ACPI suspend type changed from S3 to S1
Remote wake up turned from ON to OFF

(I didn't set Sleep to 'never')


Power Options control panel

Changing the advanced power options 'allow hybrid sleep' was not even there as an option after having changed the ACPI suspend type setting in BIOS, so couldn't do that....

Power Options > USB > USB selective suspend was already enabled.

Power Options > USB > ,When sharing media' I set it to 'allow computer to sleep'



That was yesterday afternoon and so far it wakes from sleep just fine!!!!!!!



Thank you both so very much for your time and patience, hopefully I won't be back on this particular thread again so have a wonderful summer


(PS I shall wait a couple of days to make sure before marking the thread as solved if that is ok?)

Resurrecting old thread in the hope someone can help with identical problem.

Until recently my PC (Win 7 professional, 64 bit, operating system on SSD, personal files on hard drive, 2x Nvidia Geforce 210 graphics cards, Asus P6X58DE motherboard, 24GB RAM) was behaving itself fine. At the end of each day I'd put it into sleep and I could wake the machine up fine the next morning using a USB mouse or keyboard. I like to leave my PC asleep overnight with lots of files open that I'll have been working with during the day.

Recently when I put the PC to sleep, it goes to sleep OK but refuses to do anything if I click the mouse or keyboard. If I press the PC power on button the button lights up and one of the fans comes on quietly. The monitor however remains in standby. I have no idea if the PC is actually doing anything or not, and the only way to get back to Windows is to do a forced reboot. This makes something happen as all the fans come on, but there is no POST "beep" and screen stays blank. I have to do a second forced reboot to get the POST beep and bootup into Windows.

I've tried pretty much every power configuration I can think of under Control Panel/Power management but can't make the wretched thing wake up properly. My chipset driver is the latest, my Nvidia graphics driver is the latest (though I even uninstalled it and installed an earlier version without solving the problem), as far as I know my other drivers are all up to date. Hibernation is disabled due to having an SSD and not wanting to write the Hiberfil.sys file to the disk whenever I startup, but if I activate hibernation I have the same problem only I get "Resuming Windows" rather than "Starting Windows". I've tinkered with disabling Windows Aero, no joy.

In desperation I made a Macrium backup then reinstalled Windows 7 from my original DVD from about 3 years ago, and set it not to do any Windows updates. I tried putting the naive, three year old, no updates-since-DVD PC to sleep, but sleep options were greyed out as there was no video driver. So I installed the latest Nvidia graphics card driver which enabled sleep as an option. And I tried putting the PC to sleep. Guess what - it wouldn't wake up properly, a fan came on as before but monitor remained in standby until I did two forced reboots. Oh, and that was with connecting the monitor via VGA and HDMI in case the type of monitor cable made a difference, too.

I've tried setting BIOS to S1 rather than S3 and this causes the monitor to go into standby and the PC fans to remain spinning. The PC comes straight out of sleep without problem, and the monitor springs back to life. So it's clearly an issue with S3. For power consumption reasons I don't fancy leaving the PC in S1 whenever I'm not around, but it's the only way I can get it to sleep and S1 isn't really sleep. Please can anyone suggest any other things to explore so I can get my PC to wake from S3 sleep again?
