Dell Precision T3620 starts up again on its own after seconds after entering shutdown or sleep.
I have a Dell Precision T3620 (which I've had for over a year). A couple of months ago, I bought and installed a Seasonic Focus 750 watt PSU in it. I used a 24-pin to 8-pin adapter from eBay (the one I got was recommended by a Tom's Hardware forum member). About a month ago, I also bought and installed an NVIDIA RTX 3060 GPU (which plugs into a PCI slot on the motherboard and is powered by a cable connecting it directly to the PSU).
I don't know if the problem I now have started directly after installing the PSU, or only later after installing the GPU. I can't recall exactly when it started. But many times, when I either shut Windows down or put it in sleep mode, it will fully shut down as it should (after the fans, hard drives, etc, go silent, the PSU even makes a click that sounds like it turning off), then after about two seconds of the computer being dead silent, fans will start whirring and the PC boots up. Usually, shutting it down or putting it in sleep again immediately afterward works properly, although one time, it took three tries to make it go to sleep instead of just two. Sometimes when it's in sleep mode for the night, it will also randomly wake up at some time during the night or early morning.
Fast boot has always been disabled in my computer, and I went through device manager and disabled various devices (mouse, etc) from waking the computer up, yet the issue still persists.
I'm inclined to think that likely the PSU, the 24-pin to 8-pin adapter cable, or the GPU is causing the issue (probably due to some quirk of compatibility or lack thereof with my Dell computer), although it's possible that something else is the culprit.
What are some likely causes and solutions?

@mazzinia_ Well, I may have solved the problem now. I took another look through BIOS and found an option called "USB Wake Support" that was enabled. I disabled it, and since then, the computer has stayed shut down whenever I shut it down. I still need to try shutting down the computer and putting it in sleep mode a few more times to be sure, but it's starting to look like that was the issue.
If it does seem after a few more tries that this fixed the problem, I'm wondering if I should cancel the Amazon order for the CR2032 (if it hasn't shipped yet).

Try disabling in bios the feature to power on after a power failure

@mazzinia_ I checked and it's already disabled.

Have you considered reverting to the configuration prior to the 3060 , to check if it's actually related to the gpu somehow ?

Actually, the unit has a few years ... try changing the cmos battery first

@mazzinia_
It's something I might have to try if no more simple solutions work.
Would I need to uninstall the NVIDIA drivers, or would removing the GPU and temporarily using the integrated graphics (or maybe even just switching to the integrated graphics without removing the 3060) be an acceptable place to start?
That might be a good idea, if it's affordable and can be done without significant risk of damaging my system.
Where would I buy one?

By the way, how likely is it that a failing CMOS battery could cause this type of issue?

@Rocketeer it can cause a lot of issues. The battery is also very cheap

@Rocketeer removing and using the integrated temporarily. But first try changing the cmos battery

@mazzinia_
I've read that a failing CMOS battery usually causes problems with the PC's displayed time and such, and I haven't seen any of that. But it could still be worth a try.
Is this the right one (and a good price for it)?

@mazzinia_ Is Duracell's CR2032 (currently $5.69 on Amazon) compatible?

@mazzinia_ I've ordered a Panasonic CR2032. It's supposed to arrive Monday (although delays sometimes happen).
Regarding testing if the GPU is the problem, I didn't mention earlier that before I installed the new GPU (an NVIDIA RTX 3060), I was using an NVIDIA GT 1030 for over a year. Would it be better to put the 1030 back in (which is how the computer was since I started using it) or to leave both GPUs out and use the integrated graphics (as we discussed before, but which I've never done on this particular computer before)?
Also, since both GPUs (1030 and 3060) seem to use the same NVIDIA drivers, would it be safe to swap them without uninstalling and reinstalling the drivers? I uninstalled and reinstalled the drivers when I installed the 3060, but I'm not sure whether it's really necessary.

uhmm, that option is to allow / disallow waking the pc using the keyboard. Well, if it was that, better... personally I would change the battery anyway ( it should be on the low as charge ) but if everything works as it should, you could indeed wait and cancel the order.
