I recently found out easytune is causing lots of problems. I do not know exactly when or which program caused the problem. When I want to click siv, it says easytine is restarting please wait, it hang for indefinitely time then I have to use process manager to close it, easytune would not open. Next time I start app center try to click on easytune. I would see error message
I tried uninstall everything from gigabyte then reinstall app center. Still same.
Now I tried to uninstall everything from gigabyte then reinstall from original CD come from motherboard. I changed bios onboard graphics from pcie1 to igfx. Then in app center when I click on siv and easytune, they would not open and no error message.
