Where is the video or graphics card located? I'm not a "computer" person but I was able to open the CPU case. I am getting NO SIGNAL on my monitor but the computer seems to be turned on and it sounds like it goes through the entire boot up but NO SIGNAL on the monitor.
Can someone tell me where the video card is located? IT seems from other posts that people are suggesting this might be the problem. Thanks!
it is on a white slot in the back of the pc near the i/o input panel on the back of the case and if u don't have anything on the slots there then u don't have a vid card and u have integrated graphics which means the problem isn't the vid card.
for the lights u may have to make sure no connections are loose on the mobo, the big green or whatever color board that stretches across half the case
Easiest way to find the video card if you know nothing about PC components: Find the thick non-power cable that connects the monitor to the back of the tower. It's either a VGA cable or a DVI cable--both thick with big connectors. Usually the connectors are blue or white. If the cable plugs into your motherboard at a plug with a screen symbol, then you have onboard or integrated graphics and you should get the motherboard looked at (and likely replaced).
If the cable leads to a separate card that plugs into the motherboard, then you have a dedicated video card. If you're getting nothing at all on the screen, this part probably needs to be replaced.
It could also be that the monitor stopped functioning--you can try using it with another computer to be sure.
Also make sure that everything is plugged in and powered--it's odd that your mouse and keyboard don't work.
If you can't easily diagnose the problem then it might be best to call a repair shop or a relative who is more knowledgeable about computers.
