PC turns off when put to sleep

[Ookiie]

Hi guys, I've been reading this forum for years now and I always found the answer to my problems, but I haven't found anything about this so here I am, making my fist post 😀
So here's the deal, I just upgraded my motherboard from some cheap ass MSI AMD760 chipset, that shouldn't even run my processor but survived for whole year and a half, to a bit better MSI 970 Gaming motherboard (I also changed the case and a new cooler, but I doubt that affects the issue), the rest of the stuff remains the same.
And I came to the first and actually only problem with the mobo, when I put the pc to sleep (either the hardware button, software button in windows or keyboard button) the pc just turns off, that is off, without the power LED blinking and there's usually recovery options when turning it back on, saying windows did not shut off properly. And I really got used to putting my pc to sleep instead of turning it off, even if the boot takes about 10 seconds to fully load everything, as I love the fact that I can press the button and use stuff where I left them right away. So first thing I did was to reinstal the windows, as a lot of people said changing the mobo can cause issues if not making a clean install of windows, but that didn't help, still the same.
I have disabled hibernation in power options and even through cmd command so it's not even available to choose. In BIOS S3 is enabled and in windows using cmd powercfg a command it displays s3 as supported.
I have also tried enabling/disabling all cpu features in BIOS, like s1e, core 6 state etc, all returning the same result. Disks are running in AHCI mode.

Here are my other specs:
AMD fx8320
MSI 970 Gaming Motherboard (amd970 chipset)
MSI AMD7850 2GB
Samsung Evo 840 128GB SSD
Seagate 160gb 7200rpm HDD (my old one died so I use this one from a really old setup until I get the money for at least 256GB SSD to go fully solid drive, there's nothing installed on it, only for music, pics and movies)
8GB kingston 1600mhz RAM
550W LCPower PSU (this is THE weakest spot in the setup, and I already ordered an antec VP700P psu and it will probably arrive by the end of the week, but sleep worked with this same LCpower psu on the old mobo, so I'm not sure if it could be the cause)

all drivers are the latest, windows 8.1 pro 64bit, freshly installed, genuine of course.
Is there anything I could have missed in the options, or anything that could be wrong?

Thanks in advance and sorry for the long post, but I wanted to provide as much info as possible.

well the kernal 41 error just means windows shutdown improperly, it actually doesn't mean anything else.

have you tried updating the bios on the motherboard. sounds like a bios bug.

 

[Ookiie]

yes, totally forgot mentioning BIOS in the post, it is already updated to the latest version available.

 

[ingtar33]

did you properly install all the motherboard drivers for your new motherboard when you installed it? it can be iffy upgrading a motherboard without a windows re-install.

if you go to control panel -> power options; click on change plan settings, then change advanced power settings
you can turn off sleep mode all together
start with hard drive, enter 0 for how many minutes prior to sleep (0 means never)
then move down to Sleep, and change all the values to 0

that should turn off sleep mode. you can still put the monitor to sleep if you'd like, this is probably the best you can do because it sounds like there is a driver or bios issue causing your pc to shut down when it goes into sleep mode. If you can't find the driver to stop it, and you have the latest bios, simply turn off sleep mode.

yes I installed the network driver from the dvd I got with the mobo, and then downloaded all the newest drivers from msi website under my mobo support page, and graphics drivers from AMD website, and I just updated the network driver as I was running an older version from dvd when I wrote the fist post, but didn't fix the issue.. I'll wait for the PSU to come and see if that fix the problems as it really looks like power gets cut off when entering sleep, so I will update this thread then.

It does appear to be a PSU issue as you suspect.

Other things to try for now:
1) update BIOS if newer exists

2) ensure CPU and memory or using DEFAULT settings

3) run MEMTEST www.memtest.org (let run through the night to also see if system crashes due to power)

4) Reinsert all cables, especially POWER

I'm about 80% certain replacing the Power Supply will solve your problem though.

I got the new PSU and it solved the problem, thank you for the answers
