  1. Power supply is certainly a logical suspect...

    (a shorted component will cause a PSU to switch itself off too, so, you might try disconnecting cables from internal SATA hard/optical drives, and , even unnecessary USB cable headers from mainboard just to rule out those as being possibly shorted. (If you have an onboard GPU to fall back on, you can remove the add-in GPU to rule out it being shorted as a cause, but, a weak PSU might also work if GPU is removed as well)

  2. 3 beeps on a MSI suggest it is Memory. If switching out sticks is partially helping then perhaps see if you can get an independent stick from somewhere else to test.

  5. OK - Reading around a little more - try a CMOS reset and retry. I think the CMOS reset is placed between the two PCIe slots near the CMOS battery.

  7. If the comp was working fine before did you add any new devices or made any changes to the operating system or any other configuration (BIOS)?

    According to MSI (https://forum-en.msi.com/faq/article/bios-beep-codes) 3 beeps is a problem with the memory. Though you have tried placement alternatives you may need to consider trying another stick from somewhere. If possible, pop down to your local tech store and ask them to test a stick on it, if it works, you may need to purchase.

    Sorry dude, thought that this might get it, it had been a "cure" in a similar thread but not this time. Try getting an independent piece of memory (borrow it if you can) and test with that like Saas1980 suggests.
