I recently installed new ram sticks and a new cpu cooler after trial and error it booted up for about 15 minutes before all the USB ports stopped working and I was unable to use my keyboard in mouse then the Ethernet cable went out aswell I was forced to shutdown the pc and when booted back up the power supply fan would spin and LEDs turned on but nothing else case fans didn’t spin cpu fan gpu fan nothing, I found that taking out the cmos battery and re inserting fixed it for about another 15 minutes and then it repeats the process of usbs turning off etc… does this mean that I need a new cmos battery or is the motherboard just dying or anything else??
