Graphics card no longer being detected
Hello, I am having problems with a ASUS GTX 670 2gb. I have only been using this card for 3½ to 4 years with slight overclocking. Yesterday while I was playing a game (CS:GO) my computer shut off as if it had lost power and then tried to restart itself after a few seconds and seemed to go in a restart loop. I held the button down and found that I was getting no signal to my monitor but could tell I was booting into windows. I plugged into Intel integrated video and and my screen started working so I opened up device manager and only the integrated video was showing up under display adapters. I have swapped graphics cards with an older computer. I can't seem to get a signal from the 670 in the older build, while the old AMD 4870 that I put in my newer machine is working just fine. The fans on the 670 spin normally and 2 led lights next to the power connectors light up normally.
I called ASUS support and confirmed that the card is out of warranty. I'm not sure if the problem with the graphics card is something that could be easily troubleshooted on this forum and fixed, but I figured I would give it a shot before I go out and buy a new graphics card. If you have any suggestions please let me know.
