Hello guys, so today i bought a new PC fan from Crossair, when i tried to plug it into the case i realised that the fan has a 3 pin connector and i only have a 4pin socket in my case, so i decided to put the 3pin cable into my 4pin socket, when i tried to turn on the pc, everything was working perfectly (the case, mouse and keyboard lights were all on, i could also hear the graphics card working) my monitor was turning on as usual, but then a screen popped up and it said "No signal", i tried restarting my PC, removing the new fan that i bought, and I changed the HDMI cable, i still can't find the answer to my problem, recently i was often getting this problem but after turning of my monitor for 20 seconds it was already working again, now i have no idea what to do :/ please help, thanks in advance
