Ok, so recently I got a new PSU and Motherboard for my computer and got everything up and running a few weeks ago. Everything was fine until this week when I've noticed some things. First of all, I have a Logitech G703 mouse. When I plugged it in to charge, my computer got the blue screen of death and restarted. I didn't think much of it until it happened again when I unplugged the cable from my mouse. Another cause for concern for me is that I've recently started to stutter in games where I usually wouldn't. Examples being Fortnite at the highest settings, which used to run fine at a solid 80-90 FPS, now gets random dips into the 20's out of no where. A world of mine in Minecraft has recently begun to lag much more than it used to. I usually run the game at a locked 144FPS but now for some reason in this world I get in the 30's. If anyone can point me towards a fix to either of these problems that would be greatly appreciated as I do not have a clue as to what's going on.
