Solved Sudden High Cpu Usage 90-100%

  • 3

up until 25/03/2017 i have been able to play games with 20-30% cpu usage though now when i try to play cpu usage is 80-100% and causes the game to be jittery/laggy it also causes my computer to crash, even sitting in the menu screen with the game minimised it uses 94% of the cpu. i have an i7 6700 with a kingston 16GB kit.

      Your 12Volt reading is fine in your BIOS at idle and it is a quality power supply. Your temps are good. Your internal GPU is 0.000 I assume because it is disabled due to your graphics card being your primary graphics. I do not see any special reason for the crashing but it does appear to be hardware related. Here are a few things that MIGHT make a difference:
      (computer off and unplugged, ground yourself of any possible static charge)
      Clean the contacts on the memory with a soft pencil eraser, then pop them in and out of the sockets 4 or 5 times to burnish the sockets.
      Remove and reseat all connectors 2 or 3 times each including the modular ones on the power supply to rub them clean.
      Run Memtest86 to test memory, run through all tests at least once.
      Run your SSD management software to be sure it shows no issues.
      You can run it for a while in Safe Mode or off a Live Linux disk (not install) to see if you get the crash which may confirm it is hardware related.

      Software related:
      Run Task Manager and under the Processes Tab identify the program or process that is using a lot of CPU. If you are not sure what it is, Google it. If it is not yours, not a necessary part of the system, you may want to uninstall it. If it is a program that you use but not continuously, go into its settings and uncheck “Start With Windows”, restart the machine and see if it makes any difference. You can also run CCleaner and use its Start Up feature to manage your start up programs. Please note that running the CPU at 100% for a reason is not bad and should not cause a crash unless it overheats or becomes starved for current.

      CPU current related (Increasing the voltage slightly will lessen demand for current):
      If the CPU is reaching a state that is unstable under full load then it may help if you manually increase the VCore voltage by a very small amount (0.01 or 0.02) and see if it makes any difference. Here is something that may help you be more comfortable adjusting your VCore (CPU voltage):

      Check Temps after adjusting voltage but a small increase should not effect it significantly.

      You have to be a little bit crazy to keep you from going insane.
