i tested the psu with the paper clip trick and it worked but i put the system speaker no beeps but does the paper clip trick actually tell if the psu is still good i also removed everything leaving the cpu cooler no start
The only thing the paperclip trick does is verifies that the PSU does in fact start. It cannot verify voltage or amp levels though.
RAM does not normally cause power on/power off, it will cause a no post. GPUs tend to also do a no post.
The last system I had at work doing this exact same thing turned out to be a bad motherboard.
