my nerds, i call upon thee for help once more. my computer popped yesterday, fortunately i was *literally* ordering a new one when this happened so it doesnt rly matter. but see, i wanted to sell some of the old components, so i need to know what went pop
it popped when i had the case open and the power disconnected, when i plugged the power back in my speakers went THUNK (not unusual), and when i powered up my pc all the lights flashed for a sec and then, nothing,,,
ive tried a new cable and the same happens. if i mash the on button a bunch of times nothing happens, but if i wait a few minutes and then press the on button, all the lights flash (including peripherals) and the fans jerk for a sec but then it goes off again. any ideas what ive fried??
@envgen Given that after waiting some time, you could power it back on again, however briefly, I suspect the most likely culprit is the PSU. It hasn't COMPLETELY popped yet, but definitely there's something wrong because it keeps tripping its own systems to prevent further damage.
Normally, PSUs are designed so unless they catastrophically fail (blue smoke etc), they won't fry anything else, and modern motherboards often have protection built in for that too. Try a different PSU if you can?
@Nine ive got the new psu for my new build that came today, thats not going to get damaged if i test it on my old potentially dead pc is it?
@envgen Unless ther'es some serious damage causing a massive short that feeds back into the PSU on the motherboard (ridiculously unlikely, you'd probably be able to see the damaage too in that case), and the PSU itself doesn't go "UHHH FUCK NOPE NOPE NOPE NOPE let's just put a stop to THAT" and turn itself off as well to prevent damage, then no.
The worst that will happen is that the machine won't turn on at all, meaning it's likely the motherboard in which case.
@Nine i tried the paperclip test and it did nothin'. gonna try the new psu
@envgen yeah that blocky zappy boi is dead rip :<
@Nine put in the new zappy boi, ITS ALIVEEEE
@Nine slightly concerned by quite how many cables come with it, many of which i dont even recognise, but i think ive plugged in the ones i need....????
got a bit emotional when i found it still comes with a floppy cable 😿
@envgen modular PSUs are like that. they do like to make sure you got more cables than ya need. also aaaa floppy cable ;w;
@Nine thanks for all your help pal, you have saved me £80-£100 in components i can resell 
@envgen hey no problem. ^^ Glad everything is ticking along nicely and that you didn't have to spend extra money ^^
@envgen Regardless, pop the PSU out, or have a quick sniff near the components. Chances are you might smell a sort of mixture of burned plastic/silicon and copper, or see bulging transistors. I've had several PSUs do this, after a long time of use, and had to replace them. THe first time, I thought it was something else... then the PSU popped terminally, and took out my mobo as well. ._.;
