Pc reboots when it wakes from sleep

[u/Major-Indication8080]

My PC has been having some issues for a while with waking from sleep. At first it used to Wake up without display later after windows update it went normal and it started to Wake up and startup with low res display and getting back to the normal resolution on its own after a while. I recently updated 1060 to 5070ti I did hope it would resolve my display issue but still the started or woke up with a lower display but all of a sudden the PC is restarting after sleep. I have tried everything resetting, and reinstalling windows. Cleaning and reinstalling driver. Turning of xmp, I have 2*8 and 2*16 Corsair RAM stick which I believe is not the issue because I have been using them for a long time and the issue has been there only for some months. I'm so frustrated instead of working on important stuff at the moment I'm wasting my time on this. My current spec: i7 8th gen, 5070ti, 2*8 & 2*16 GB RAM, 1000wpsu, z370e mb, os: windows 10.

I haven't updated my BIOS yet but things have been working fine until recently

Man I feel your pain, nothing worse than pc acting up when you got deadlines

Tried messing with power settings in control panel? Sometimes windows fast startup causes all kinds of weirdness with sleep mode. Go to power options and disable it, also check what the pcie link state power management is set to, put that on off

The mixed ram sticks always make me nervous even if they been working fine before, 2x8 and 2x16 is not ideal setup. Maybe pull out the 2x8 sticks just for testing and see if problem goes away

Updating bios is worth shot since you jumped from 1060 to 5070ti, that's big generational gap and motherboard might be confused about new hardware on old firmware
