i recently had to my PSU, as my old one failed. so i bought a new PSU and completely re-built the computer. when i tried to turn it on, i realized the lights lit up, so my old PSU was definitely broken. but when i tried to turn it on, all the lights and fans started to spin, but a weird noise happened, and the fans and lights turned off. a weird smell happened as well, but i unplugged it straight after this happened. i replaced the thermal compound, as i figured it hadn't been replaced in years and could possibly not be making contact between the CPU cooler and the CPU, although this didn't work, as the same problem happened again. it shouldn't be my PSU, as i've only just replaced it. all videos online say that i have built the PC correctly, and everyone else seems to think the culprit could be the PSU, even though i've only just replaced it. PLEASE HELP!!!

it smells when i try to turn it on, makes a weird noise, and then shuts off again. im not sure whether the smell is coming from the CPU or the capacitors on the motherboard. also what part are you saying has probably died?
