Hi everyone,

I was trying to see if my old R7 370 is working so I put it in my perfectly working PC (after DDU driver uninstall). Pc did boot but didn’t post image and the troubleshooting light on MB said that GPU isn’t working. Ok, so the GPU is dead, I turned PC off by pressing case button. Switched my regular GPU back but now nothing is happening, PC isn’t starting at all.
What I tried:
  1. Connecting the pins to power on PC directly from MB
  2. Clearing CMOS and removing battery
  3. Trying different PSU
  4. Checked cables
  5. Tried other PCIE slot
Any advice would be greatly appreciated.
Thanks in advance :)

Welcome to the forums, newcomer!

When posting a thread of troubleshooting nature, it's customary to include your full system's specs. Please list them like so:
CPU:
Motherboard:
Ram:
SSD/HDD:
GPU:
PSU:
Chassis:
OS:
Monitor:
include the age of the PSU apart from it's make and model.

Trying different PSU
Include all spare parts used during your troubleshooting process, in the PSU's case, also include it's age.

You didn't mention which unit was initially used on the build.

PSU: Thermaltake Smart Se 530W 2015
That PSU is not exactly a PSU, more like an expensive paperweight. Try and borrow a reliably built, branded PSU that has 650W at the entire system's disposal and see if that alleviates the issue.

When you used the EVGA unit, did you make sure to remove the Thermaltake cables?

As for your board, can you walk us through how you cleared the CMOS?

I was using EVGA PSU when testing the R7 370, Thermaltake was in the PC before, I recently changed it, but it was still working last time I used it, so I tried powering PC with it also.

Yes I used only EVGA cables for EVGA PSU.
I removed the battery and shorted the two pins to reset CMOS, after 10 minutes I returned the battery. During all this, PC wasn’t powered, it was disconected from the wall.

Thank you for answering!
