I built a new computer about a year ago, and ever since I built it, about 1/5 times I boot, I will receive very strange lag while playing any games or watching any movies. The games will run as if they are at 1FPS and lag with such a hitch and stutter its unplayable. Movies will do the same, skipping as if it was a scratched DVD. The only way to fix this, is to completely turn off the computer, and after shut down press the switch on the back to remove power to the PSU. After several seconds I can turn it back on and it will run normal and as fast as it was before. I have never experienced this with any of my prior builds or with any friends or family PC. Does anyone have any idea what this might be? Iv looked through google for answers the best I could and have replaced the CPU fan with a new cooler master fan, bought a new cooler master case for better cooling (thought it may be a cooling issue). None of this has worked. Any tips or suggestions would be much appreciated and welcome. THANK YOU!
