Question Computer fails to wake up from sleep mode ?

[Disheveled_Human]

Hello, my computer works perfectly fine but sometimes when I try and wake it up from sleep mode it fails to do so, then power cycles 3 times and does a full boot? I have tried waking it up by mashing the spacebar/enter key, mashing the left click and even using the power button on the tower and just sometimes it works, sometimes it doesn't. The hardware is all new and up to date and i have no issues outside of this one.

Specs:

ASRock H610M-HVS mobo
Intel i7 12700K 12th gen
Nvidia RTX 3070ti Asus TUF
T-Force 2 x 8GB RAM clocked at 3200MHz (mobo's max speed)
Kingston 1TB SATA SSD
PSU: Gigabyte P650B

Have you tried resetting the BIOS by removing the CMOS battery to see if that helps? -- it could be because of a BIOS setting that prevent waking from input devices, so resetting might revert things and help.

Is your OS uptodate?
Do you have any pending BIOS updates?

The last time I had issues with a computer waking up from sleep, it was because the RAM was bad. Which was frustrating because it passed RAM tests and such.

The PSU may be suspect, but if the computer works fine otherwise, then my suspicion points more to RAM.

BIOS is updated already and OS I just updated the other day.

Hmmm, the only thing that really stands out is that this tends to happen after windows updates not all of them but some of them. I just recently updated my windows prior patch it wasn't doing that basically rinse and repeat that for the past 6 months.

As a starting point look in Reliability History/Monitor.

Any error codes, warnings, or even informational events being captured just before or at the time the computer fails to wake from sleep mode?

Or likewise perhaps started after some Windows update? Check the timeline.

Check Update History for failed or problem updates.

Also run "dism" and "sfc /scannow" to perhaps find and fix corrupted or buggy files.

no wifi cards or anything? what USB devices?

Are all drivers up to date? Could be a driver to blame, often is with sleep mode.

I have an old Asus wifi card but primarily use a wired connection the wifi is fiber and the wired connection is cable so im always online.

could be the drivers on the old Asus card, can you give me some details about its model number and I can have a dig... see what chips it has, see if any newer drivers.

could try removing it to see if it makes any difference. Driver won't run if no hardware attached.
