If the video card(s) in question has/have a power slot on them (might be a 4 or 6 pin slot) they MUST have power. Reason being, the power going to the video card power key components for the video card which without, will not work at all.
yes
no, you would need to get a new psu.
It is from power supply It is the cube with many holes for the wire It is located in the bottom left of the computer case probably under the motherboard and the video card
Any Video card on the market as long as you got a Decent Power Supply and an PCI-E X16 slot on the motherboard.
I would recommend at least 500W!!!
If you have a 500 watt power supply and you want to put in a new video card. On the video card's box it will tell you how much power it needs. If it requires less power then you don't need to worry. If it says it requires more, you'll need a bigger power supply with large wattage otherwise you'll kill your computer.
Processor Motherboard RAM (random acess menory) Video Card Power Supply and Fan
It will blow up and destroy the entire earth. No, jk, it will probably just not work.
If there is no video card, get one. If that is not the case, buy a new vid card.
the monitor works and the video card and the power supply but i don't know if its the CPU chip or the motherboard how can i tell whats wrong
Yes they both are similar
Yes, I believe it should. Just make sure your power supply has enough power for that
