|Hi, firstly, you can connect the Monitor to other computers |
and see whether it can display.
You can also check if your ram is dirty, remove the case
cover and carefully remove the ram without touching the
contacts that get plugged in. If they are dirty you can clean
them with a eraser (rubber) and then replace the ram
carefully. You may need to look at how much ram you have.
if you have a spare power supply unit, put that one in and see
if that works, this will tell you if your power supply unit is in
need of replacing. Sometimes a power suply unit can have
issues in any one of its cables, this prevents it working
properly yet will still turn on your pc.
