Tower gets blown out with compressed air on Friday. Monday it powers on, fans spin, power LED is steady, and the monitor just says No Signal. The single beep it always gave at startup is gone. Speaker is still plugged in. RAM reseated one stick at a time, GPU reseated, onboard video tried, monitor proven good on another PC, PSU rails in spec, CMOS cleared. Still nothing. The machine is not even reaching POST. What's your diagnosis? Drop it in the comments. Answer + the hands-on lab: examwizardz.app/t/28789 #it #techtok #helpdesk #CompTIA #examwizardz
