PC refused to boot when woken from sleep. Is the RAM at fault?

Just built my first PC a couple of months ago and this is the first time I faced this issue on this computer. Windows 10, Intel Core i9, Z390 Aorus Ultra, DDR4 Dual Channel 16 GB RAM, GeForce RTX 2080.

Yesterday, I had to hard shutdown my PC after it failed to wake from sleep. After hitting the power button like usual, while the PC itself turned on, there was no signal to the monitor and it just stayed that way until I performed a hard reset. It did not seem to be a monitor or graphics card issue, though I can't say for certain. This resulted in a Memory Management BSOD on startup and corrupting several C drive app and MFT index files, necessitating a disk check on another boot to fix them. Hopefully all that's fixed.

The thing is, I have been trying to narrow down what caused the failure to boot from sleep in the first place. I've looked through the dump file with WinDbg and combed through Event Viewer with no real luck other than Windows failed to resume from hibernate with error status 0xC0000001. I do have my suspicions though and this is what I want to check with you guys.

Before placing my PC into sleep mode, I had quite a number of programs running and windows open including Chrome with about 161 tabs. As sleep pushes all programs and processes to RAM, could the RAM have buckled under the heavy load and caused the computer to hang while trying to boot from sleep? Is there any way to confirm this?

Interestingly enough, I never had this issue when sleeping my previous PC that was running on Windows 7.
