So i've been having this problem for about a month now. My pc will power on but I will get no video display on my tv or monitor. I had a solid gear 600w psu and I replaced it because I thought it was bad, but I was wrong. Just now(like 5 mins ago) I installed my replacement mobo. Gigabyte 970a ds3p toreplace my msi 970ag43. This did nothing. What happens now is my pc turns on, fans turn on normally, then psu fan blows hard as f**k, r9 270x fan stops spinning and then starts again. I've had it running idle for a couple minutes and still have no signal. PLS HELP AND DONT MAKE ME WASTE MORE OF MY PAFRENTS MONEY!!!!
