Question Did my new GPU kill my CPU?

[ryanzzion]

hi everyone,

so today i bough a new GPU, the XFX rx5600 xt. installed it and expected it to boot straight up, but it didnt. it wouldnt post or even show a signal to the monitor, the fans just kept periodically spinning to maximum rpm then, slowing down, with the process repeating.

i went an plugged my old GPU back in (rx 570), and now for some reason, this didnt work either, i had the same issue of not posting and no signal, when this gpu worked before i installed the new one!

made sure ram is installed correctly, unplugged and then plugged everthing back in. i thought maybe i had damaged the motherboard. i ended up removing the cpu(ryzen 5 3600x) and replaced it with my old ryzen 3 1200 that i had in my system about 3 weeks ago, and it worked with both GPUs! my worst fear is seeming to come true and my new gpu has somehow killed my ryzen 5 3600x. it was working perfectly before installing the new gpu, so i dont understand how this can happen

note that i have a 450watt evga bronze power supply installed. im thinking that perhaps that power supply cant handle the ryzen 5 and the rx5600xt. im pretty sure the cpu is now dead however, since my old gpu doesnt work with the ryzen 5 now, when before it worked just fine.

struggling to understand how just installing a new gpu could detroy my processor like that.

any suggestions of what else it could be/ what caused it? really dont want to buy another cpu

I can't think of any situation where a GPU can 'damage', let alone 'kill' a CPU.

Put the 3600X back in, clear your CMOS and see if it boots back up with the 3600X + 570.

The power draw of the 5600XT should only be 10-20W more than a 570 (depending on the models in question) and a 3600X only adds 30W over the 1200.
It's possible that a low-end PSU cannot adequately power any longer, but a (max) 50W additional load would be a surprising 'breaking point' for any halfway-decent PSU*.

*Not saying the EVGA "450W" is a great choice... depending on the model it's anywhere from 'meh' to 'good luck', but they don't have a fire hazard in their product stack, and I'd still expect at least even a 3600X + 5600XT to post.... just maybe not be reliably powered in the long run, or support overclocking.

Clear your CMOS, and try again. If the 3600X gets back up and running with the 570, we can troubleshoot from there.

get a different PSU

bought a new psu anyway, seeing as the other one was on its edge.

hi barty, thanks for the reply.

ive cleared cmos by putting the jumper in the clear position and removed the battery. left it for 5 mins, then removed jumper and reinstalled battery. still have the same problem with the rx570

i also left the cmoc battery unplugged for the entire night. still no change

 

[ryanzzion]

right, so i did a barebones minium start and it boots to the bios. will try re-installing compnenets 1 by 1 to detect issue

 

[ryanzzion]

right, so ive isolated the issue. there seems to be a proble with the M.2 drive installed on the back of the motherboard. it only manages to boot without it.

i have noticed however that in its first attemp to boot, it fails and loses signal to the monitor, but then on a second attempt is able to boot the OS. this happens with either one of the GPUs.

why would the M.2 drive be causing this to happen?

I would try another M.2 slot. I do not know if your motherboard has another slot, but its worth a shot.
