i hope this is the right area to post this- if it isn’t i apologize. i have an omen gaming desktop and sometimes the monitor will display this error “input signal not found check video source” and the tower itself like halfway turns on? the fans turn on but not all of them and the colors inside don’t light up. i’ve done EVERYTHING. replaced the cord, cleaning out the inside of the plugs, restarted multiple times, waited, moved the graphics card to the second port. everything. i don’t know what else to do. this computer was a gift from my late mother so it’s not something i really want to replace- not to mention the cost of it. any other ideas?
