Hello!
I just bought a Gigabyte Radeon Rx 460 Windforce OC 4GB to replace the Radeon HD 7470 OEM card. I installed the new card. It seated properly in the slot. The computer will not power up at all. The "blue light" on the tower comes on for about five seconds, then goes off. Nothing on the monitor. Re-installing the OEM card makes everything work normally. Anyone have any bright ideas?

Thanks,
Les

Yes. First shut down the PC, and make sure you’re grounded. Static discharges can damage any computer.
  1. Remove the battery. ...
  2. Wait 5 to 10 minutes.
  3. Put the battery back in.
  4. Power on your computer.
