A8n32 deluxe not booting anymore

[Isura]

I've had this motherboard for about 1 month with no problems. But this morning I turned it on and nothing happens. The fans and onboard LED turn on, so I don't think it's a PSU problem ( and I bought a new 600W psu last month). I tried to clear CMOS by moving that jumper from 1-2 to 2-3, but that didn't solve it. There are no error beeps, just a black screen. What should I do next?
