For well under 20 bucks the first thing I do is maintenance. Some folk replace parts first.
Hello, 3 Years ago in 2011 I ordered my own custom built computer from CyberPowerPC. The computer could play LoL or WoW with the highest resolution at a solid 60/90fps respectively. However, towards the end of July or the Beginning of August, it started making the weird buzzing noise. I have a total of seven fans Including the one for the power supply, and one for the Graphics Card. Ever since it started the buzzing, the altogether loading began to diminish. Netflix video couldn't keep up with the audio, and the FPS on LoL will suddenly and unexpectedly drop for no apparent reason. I feel (through just a mental work-through of the problem) that the Graphics Card is starting fail. However, it could be the core or the motherboard, I don't know how to tell which or whatever the problem is.
