My computer suddenly doesn't start today (last used it last week). When start it up, it was up for a few seconds, and then it restarts itself. This happens again and again. There is no beep at all.

Is this a likely problem with my power supply?

Edit 1:

It's the memory module that's causing the problem.

Booting the machine without any memory module is fine, no restarts happen. But with the memory modules (2x 4GB) on, it just restarts again and again. How can I test if it's a problem with motherboard or with the memory modules?

That would be the obvious place to start. But could also be HDD (failing on a critical part of the boot code) or RAM (it takes a few seconds to fit the bad part).

Do a boot to go into the BIOS screens and check this also fails (eliminate HDD, and probably also the RAM), repeat after removing as much hardware as you can—reducing PSU load—to roughly check for PSU issues (this is not perfect, different power rails are dedicated, and if it is the CPU rail at fault you cannot easily reduce the load).
