Question gpu pulsing no display

Jan 20, 2022
Hi new here and need some help guys

So my pc just turned off by itself yesterday when i turned it back on it posted like 1 sec and then went off again. I removed 1 ram stick, and other stick vice versa, reseat it, cleaned it with erasers, and reset CMOS but to no avail, I was not getting any post still, Now the weird part is every time the LED on my ram lit up the gpu fan starts pulsing as if it's trying to gather some sort of power I havent seen this behavior before. Ive tried re-inserting a different gpu and ram modules but still no luck. Please help

quick specs
r5 2600
asustuf 1660 super
32gb ram
asus b450 mobo
