My computer has recently decided to stop working. I can turn on the tower and the monitor to power it up and the tower does it's normal thing like it is working, the screen on the other hand stays blank. The light on the screen turns green when I first turn it on the computer acts like it is going to work then goes amber and stays that way. The video card was replaced by best buy some time last year. I have also tried another monitor on the same computer and still get the same results. Can anyone tell me what is going on I'm a photographer and have clients photos still on there that I can loose. Can someone please help?

Hi Guardian1 and welcome to D-A-L.

I have also tried another monitor on the same computer and still get the same results.

Well, it would seem the new card is bad too, or loose, or is not getting required power. It would need to be inspected to ensure all power connections are secure, the card is tight in it's slot and properly secured, and the power supply is adequate, and provides the necessary connections. We can assume it has the necessary connections since it did work. But if the supply is failing, or a connection came loose, that could prevent the graphics card from working. Some Best Buys have a good tech support centers, some do not. If not comfortable digging around inside yourself, you might want to try another shop - if not under warranty.

Since the 2nd monitor does the same thing, and you get nothing, Safe Mode would do no good either. If that computer came across my bench, I would make sure the interior is clean of heat trapping dust, all fans spin freely, and all connections are tight and secure. I would make sure the power supply is sized right for the current hardware (should not be a problem if no HW has been added since new) and test the power supply (or swap in a known good one of the right size). If still no good, then I would try another graphics card. But I would be leery of a bad motherboard if a 3rd card fails.
