code E0 - S3 Resume is stared (S3 Resume PPI is called by the DXE IPL)

What does this mean?

I restarted my PC earlier and now it wont boot. The disc drive spins up, and the RGB turns on and everything. I see debug code E0 and the yellow led is on next to DRAM. I have reseated my CPU and my RAM. I have tried using just 1 stick of RAM in multiple slots. I cannot get into the BIOS. I have tried holding the clear cmos button on the IO plate for 10 seconds, shorted clear cmos jumper pins, and switched to BIOS 2 via mobo dipswitch, all with no effect. I appreciate any tips or information. Here are some specs:

Windows 11
GSkill DDR5 6000 (2 x 16)
12th gen I7
z690 ace
3080 ti fe
2tb samsung m.2
generic 6tb disc drive

Unfortunately I am still having this problem. Can't boot, cant enter BIOS, nothin. After reading the link above, which is about bent cpu pins etc, I decided to check my socket. I can see zero bent pins or debris in the socket, anywhere. I used compressed air just to be sure. Also...this problem started after months of normal operation and hadn't done anything inside the case, so it's not likely a bent pin is the issue.

Hmm. Did you have any overclocking going on, regarding CPU or RAM (except XMP)? Can you make a photo of the board showing the CPU and RAM areas?

I have had overclocking turned on, through the BIOS with the auto-OC feature. I went back and forth with it so Im not sure If it was enabled while I was using it last or not. I never messed with any voltage settings or anything crazy. I don't have any good pics to share. I did cave and purchase a new cpu today, with no luck. Same problems.

Yeah that was a bit premature, and the board didn't even show the CPU LED, so why a new CPU of all things? If we go by what the board says, you'd need to test with different RAM.
But it might just be an issue of the board itself. Both the RAM and the CPU are much less likely to suddenly develop a fault than the board. CPU and RAM can be DOA sometimes (as can a board), but having worked before and then to stop working, that's more of a thing that a board would do.

Here's a few words about that Auto-OC "Game Boost" by the way: https://forum-en.msi.com/index.php?...wk-game-boost-is-it-safe.377809/#post-2140311

Again, it would be good if you could make a couple photos.

What i would do now is the following, strip the system down to the bare essentials: Board, CPU, one stick of RAM in slot A2. That's it. No drives, no GPU. Unplug the cables for the SATA drive, take out the M.2 drive. I know the ACE doesn't have graphics outputs, but we don't need them, we just need to see if we can get past the DRAM LED and land on the VGA LED at least.
