Windows 7: PC not able to sleep anymore

Windows 7 Home Premium 64-bit SP1
PC not able to sleep anymore


My custom built desktop PC always worked without problems.

Recently, it started rebooting after some time of inactivity (without a BSOD) and then it wouldn't start, saying that the hard drive was invalid. I had to cold boot it in order to properly start Windows.

I assumed that there was a problem with my SSD and decided to install Windows 7 from fresh. When I removed all the partitions, the motherboard stopped recognising the SSD: it would hang in the BIOS detection process. I tried the SSD on my laptop and it worked fine. Puzzling! I assumed that for some reason the motherboard stopped being nice to the SSD...

I decided to use a spare laptop HDD that I had and install it on the desktop PC. Windows 7 installed fine but now, when I send my PC to sleep, it fails to wake-up properly and always says that Windows didn't shutdown properly, and does a clean start. Hibernation works fine, though.

Might this be an indication that the motherboard had better days and might be giving up? It's 8 years old, but it's still provides the performance I need.

Does any of you have an idea of what might be going on?

Thank you!

Windows 7 ultimate 64-bit

I would try going to the support site for your motherboard and re-download the latest chipset drivers. Because chipset drivers basically tell the mb to detect what type of hardware is connected to it. So give that a shot and see if it works for ya. if not post back.

Hi All, I have two systems a N650SLI-DS4 and a GA-EP35-DS3L hooked up to a Trednet KVM switch. If I put the GA-EP35-DS3L to sleep and switch to the N650SLI-DS4, the GA-EP35-DS3L system wakes up. The only way I have been able to keep it in sleep is if I hold the switch for the N650SLI-DS4 while...
