Question PC keeps restarting with repeating beep

[Wintah3770]

Everything is new, I've cleared the CMOS, Pressed MemOK! (Just restarts and does the same thing),
When I remove the ram I get no beeps but fans, when I place 2 ram sticks I get no beeps but fans, only when I place one it boots into this loop with the beeps.

Parts (can't find psu but it's new and came with case):

Are you putting the memory in sockets A2 and B2? (the second and fourth slot from the CPU)

Yes they're placed correctly, I just took the mobo out and put it on my table and it's running, I think the mobo was either in contact with the case or the screws that hold it in place, what could I do to fix this?

First try just putting everything back. Could be a transient issue.

" -When installing total memory of 4GB capacity or more, Windows 32-bit operation system may only recognize less than 3GB. Hence, a total installed memory of less than 3GB is recommended. -The default DIMM frequency depends on its Serial Presence Detect (SPD), which is the standard way of accessing information from a memory module. Under the default state, some memory modules for overclocking may operate at a lower frequency than the vendor-marked value."
This is the fine print at the end of your most recent Memory QVL list

Double check that your RAM's serial number matches the RAM listed on the QVL list. I'm not sure if it matters, but your particular BIOS revision and current OS may have something to do with RAM compatibility.

RAM is fine I've booted it off the case

I did, plugged power cables, gpu and speaker, no screws and it booted fine.

I started plugging the rest like usb, audio with still no screws and it went back to the loop, what the heck?

At this stage I would recommend working from the known good configuration and plugging in the audio, USB etc 1 at a time to try and identify the culprit.

The thing is, I've got it running like with everything on the case but then if I like lay down the case or anything it just stop working and I have to unplug everything and take it out.
I'm geniunly confused.

Ah ok my bad. I misunderstood.

So the board will boot fine with ALL case connectors plugged in outside of the case but puts itself into a boot loop when in the case?

I admit it is strange but it sounds like a short of some sort to me. The mounting posts of the case are not contacting anything they shouldn't on the rear if the motherboard and are fully aligned with the screw holes? I saw this mentioned earlier is all but wanted to clarify.

Have you tried removing the PSU from the case and trying to boot the motherboard etc in the case? Just be careful incase the PSU is the issue and look into discharging it before removing it

It can boot in the case but it's hard to reproduce,

When the motherboard board is fully alligned with the holes it can boot, but sometimes it can't, and when it can't I just need to unplug everything, and replace it and it magically works, I don't know if it's any sort of bent cables that make this happen or not.

I'm really trying not to remove the PSU because I'm not really familiar with PSU's, maybe as a last effort.
