1. Is there any beeping sound comes out when u power ON ur PC?
    If do, how is the beep sound? One long beep or 3 short beep?
    If one long beep, means ur RAM losen. Take the RAM out, use rubber to wipe the RAM
    leg, then plug it back.
    If 3 short beep, means ur graphic card losen, same take out, wipe the leg with rubber,
    then plug in back.

2. If power ON dy, is the boot up beep sound got or not? and the HDD LED light got lights
    outs?
    If above 2 check dy, on this part Monitor still no display, and the HDD is running till boot
    into windows desktop, this means ur monitor KO dy. Time to change.
3. Check the VGA cable on both side whether is connected properly.
    If either side nt connect properly, just plug back properly oni.
