I was using my computer, it froze and wouldn't accept any commands. I turned it off through the PSU and left it there. After that it didn't turn on anymore. I've tested a different psu, I've changed the power cable, I've tested taking out a memory stick and putting it in different positions, I've tested a different gpu.
It turns on the CPU light, goes to the DRAM light and stays on them for about 10 seconds, and when it goes to the GPU light it stays on for about 2 seconds and restarts, after that it alternates between the CPU and DRAM light.
but at no time does it show video
