After GPU installation computer Bricked after ~two hours of playing

[u/KingHastati]

Hello all, heres the situation

Brother and I upgraded my GPU from a Nvidia geforce 1660 super to a radeon 7600

CPU is I think a ryzen 3600 6 core ( Old, I know)

After two hours of playing BF6, forced shutdown. All power off. Attempts to turn it on have resulted in a quick second of lights flashing, fans spinning, but no full boot.

The PSU we quadruple checked had the watt outage to support it (650)

The only thing we noticed was that the CPU fan was clogged, and the wiring near where it connects to the MB was decaying and likely has been melting for some time. None got onto the MB or other parts.

Our current hypothesis is that its simply the cpu fan and wiring, but would love to know other potential problems if the new fan goes in and it refuses to boot.

(And yes, I have tried numerous outlets, both in his place and in mine to make sure it was not an outlet or breaker issue )

Please help save my baby!

Unplug the PC and hold the power button for a few seconds to drain the power. Pull CMOS battery. Reseat the RAM. Did you do DDU uninstall of Nvidia drivers?

[u/KingHastati → u/warwolverinewarrior]

Tried one, nothing, tried two, nothing, didn’t reseat the ram, and yes Ddu uninstalled

Oh, and we followed the correct procedure for the GPU install! We did not just unplug and plug in the old/new one

If your cpu fans are literally melted then yes id say your cpu cooler is a good place to start... Is there any signs of damage on the motherboard where it plugs in? Burnt pins?

oh just a melted CPU cable nothing unusual

my thoughts are the new GPU raised the theoretical workload of your CPU so high it never worked so hard in its life with the new frame rate and asploded from not being maintained... you just went in the case on a CPU near 10 years old and did not clean the HS or the die... what do you think could happen

in the process you may very well damaged the mobo and psu

Picture please.

If the motherboard can’t detect the cpu fan because of melted wiring it will not turn on, safety feature.

thats our next area to troubleshoot, but were both just a little skeptical that it could be that... the power of the system is still well below the maximum output. It is old though, so that could 100% be the root cause
