Okay so, today my r9 290 finally came in, I ordered it 2 days ago. What I didn't realize before I bought it is that my psu has 2 rails instead of the one that I thought it had, it is a seasonic S12 620w bronze. So my next mission was to try to get the gpu to balance out between each rail. It was kind of a guessing game since the pins aren't labeled at all but I think I came up with a solution. I used the 4 pin adapter that came with it and then used a 6/8 pin with that. I turned it on, and it worked absolutely fine. To test and make sure I was successful I ran Fur mark and prime 95 for 2 hours. It ran perfectly. I stopped the testing and played bf3 with a friend for 30 minutes then stopped and browsed newegg just for fun. As I was browsing my screen suddenly went black. My fans were still running, including my gpu, but there was no display, nor power through the USB. I could tell because I have external hard drive that was plugged in and the light was off. So what happened, did my psu get overloaded? If it did, why? It handled my computer maxed out for 2 hours, why quit 1 hour later while I browse newegg I know I'm cutting it close with the power supply but my system doesn't draw much without the power supply. Here is my build.

I5 4670
12gb's of ram
R9 290 vapor-x
1tb seagate hard drive.
620w seasonic bronze psu

What's happening to my system and how can I fix this. Don't just tell me to buy a new psu, because I would like to avoid doing that.

Thanks for the help.
 
Solution
Check if the HDMI/DVI Wires are not broken.
Try re-seating them (Unplug it and plug it)

If thats not working, remove your GPU and plug use your CPU's Integrated GPU to see if it's the card.

Hello , I am having similar problems . My gpu worked fine for 2 to 3 months . But now I face random signal loss leading to motherboard freezes . Sometimes I get white or pink screen . But when I removed the gpu everything was fine for the whole day . No problem . Does this mean gpu problem . It's still under warranty
