The long story short (r9 290x reference)
I replaced the stock cooler with my old directcu ii from a r9 280x after sanding down the parts where it needed.
I had to lenghten the wires so it can reach the card's fan terminal.
For the first try the card started,fan started,everything was working, i was like hell yeah, even temps were around 50C degree
I tried some load on the card when a cable came loose from the lenghtened fancable and something in my pc made a quiet pop and it shut down.
Pc boots and everything seems to be working exept the card.
I did fix the cables and rechecked every cable and soldering but the card doesn't turn on only the fan.
No signal and it doesn't heat up anymore.
I checked the caps and saw nothing out of ordinary
tomorrow check the card in an other pc
I would like to know what parts should i check or any advice getting it working again
