So I built this PC months ago and installed Win7 on it. It ran just fine until I encountered some trouble running a few games, upgraded to Win8.1 and have all my games working. But recently Win8.1 would run kinda slow. I'm not talking about game performance as I usually have constant framerate. These problems occur randomly but somewhat persistant:
I really don't want to re-install the OS or do a refresh as it would be a hassle to re-install all the programs and games I already have. Thanks in advance.
- Explorer would crash (stop working) when right-clicking on items/folders. Problem still persists after Explorer restarts itself.
- That action center flag-like icon on the taskbar would say that I have problems with virus protection etc when I already have Avira installed and updated. Sometimes a pop-up would appear suggesting me to either turn on Windows Defender or turn on and update Avira, whichever I click doesn't do anything.
- Sometimes CPU load would reach 100% whenever I start a game and the game won't even start at all. Some other time, the game would start up just fine and when it does, I usually have constant framerate.
- Windows boot up a bit slower than it should, and restarting from the OS itself takes longer time than shutting down and turning it back on again.
- That one time, Windows boot up and prompted me to enter my password on the login screen. When I logged in, the background was black and I got some error. It appeared as if I did a reset on the system and lost my stuff (the colour scheme was changed to default, installed programs disappeared). Opened the metro start-menu and Windows just froze. Did a hard reboot and everything returned to normal.
- Sometimes Wi-Fi speed is slow, compared to my Win7 laptop.
- maybe more but I can't remember for now...
