I really want to know why this has happened to my PC.I only had it for 3 weeks now.I turned my PC off to install some LED strips.Plugged them in and switched the PC back on.The LEDs worked,all the fans including GPu fans were spinning constantly which they never do(only when booting up for about 10 seconds) I but I don't seem to get anydisplay,my monitor says there's no Display cable or HDMI connected while there is.Then when I tried switching my PC off with the case power button nothing would happen.I have to use the PSU switch to do so and still gives the same result I tried unplugging GPU,RAM sticks. Tried taking out the cmos battery for 10 minutes and plugging everything else back in Tried taking all the cables out for 10 minutes with the PSU switched off and it still doesn't do anything. Any suggestions on what the problem could be? I took out the LED strips as well,didn't work.. Specs: Ryzen 1600 Asrock ab350 pro4 atx gigabyte 1060 3gb windforce 16gb ddr4 lpx ram
instead of taking the cmos battery out can you try the jumper to reset the bios? also are there any mb code lights on, or error code beeps?
