At a year the PSU could lose capacity. But the details are missing. Add the exact make and model of the PSU and GPU. Also, if this GPU was installed in some HP/Dell, make and model there as well.
I can't fine when the GPU was installed so did it ever work?
Everything in my computer works perfectly except my graphics card. When I turn on my pc the only way to get any sort of input is thru the motherboard, otherwise all I get is a black screen if connected to graphics card thru HDMI or dvi. Also, graphics card DOES turn on in the beginning but fans stop spinning and it turns off about 5 secs later, any ideas what's going on? I've tried updating the drivers at least 4 times, I've also completely wiped my pc and uninstalled the drivers/reinstalled without results. Could this possibly have anything to do with my power supply not being powerful enough (500W) or is it a direct gpu problem? (I've been using this pc for a little over a year without any problems, same hardware) thanks for any help guys!
