The problem I am currently facing is that my pc starts freezing randomly for like 5 minutes and then works perfectly but after a while it freezes again it happened before twice and every time it happened I just reinstalled windows through iso file I mean by mounting it and first when this happened I reinstalled windows 8.1 then it happened again when I reconnected my cd drive to my PC whose wires were disconnected then I reinstalled windows 8.1 then my audio issue happened I opened my pc case connected a board which has 2 audio ports and 2 usb ports I connected them correctly but the freezing problem started again and I don't want to reinstall windows again if you have any solutions please give and also apparently my pc has a red light which I don't know what it does but my best guess is that when it's flashing bright no blinking theres no problem to my pc but when those lights starts blinking when I am on desktop that indicates me that the freezing problem has occurred and it actually did so please help
