Hello. I recently bought a ryzen 7 1700. I already had an rx460 4 gb and 8 gb ram. From my old pc the only things that i changed where the ram the cpu and the motherboard. So from the beggining when i played Fortnite it was all good with stable fps and just every now and then fps dropped without a reason. From 120 they went to 30-40 for about 6 seconds and then back up to 120. I didnt care so much because it happened only for some seconds and only 1 time per hour. But yesterday fortnite crashed about 3 times and fps were going again as above. One thing that also happened was every 2 minutes that passed there was a lag spike and for 1 sec fps dropped from 120 to 40 and then back to 120. This was very unpleasant because it happened constantly and you could feel the game not so smooth. Do you think i should search the problem in gpu drivers? Or maybe there is a problem with my psu because it is from my old pc?
