Resume from sleep failure - power up loop
Have a Windows 7 PC working fine for 6 months, now fails to resume from sleep every time. On attempting to resume the PC appears to go through a powering up loop (Hard disk and fan spin up) which then goes off and repeats indefinitely till you force the power off by holding town power button.
When changing 'allow hybrid sleep' in Power Settings to disable; it cured it for a few days. The issue came back, so tried enabling this setting - same result. Disabled again, same result.
Update Intel Graphics Drivers to latest. Fixed the issue again, just for a few days.
What's going on? It doesn't seem possible it's a hardware issue but am baffled.
Thanks.
