I've got a i3 6100,asus h110m-k,8gb ddr4 ram. My pc was working with the mobo graphics card, then i installed my r7 250. The pc worked, and i was about to download the drivers for it. Then the pc froze, and now, it wont boot up with the r7 250 or without it. Fans, hdd spinning, there are no beeps, no video or anything. There is a high pitch sound coming from my psu( thermaltake xp550pp 430w) before i even turn on my pc. I tried cmos reset, unplugging the cables. Could be my psu the problem? i had these components before the i3: q6600, asus p45 mobo 3x2gb ddr2 ram.
