A few days ago the computer would not start when the case power button was pressed. I did the usual troubleshooting tests of resetting the cmos battery and removing everything from the motherboard except the cpu and RAM and slowly replacing everything one by one and trying to start again each time. The computer boots and runs without problem until I added the graphics card back in. I did different configurations of components with and without the graphics card to see if that might help, but it always knocks off when as the gpu is added. I hooked up a new, larger psu (600w compared to the original 450w) to see if that made a difference but with no avail. My questions are: Is there a way to definitely confirm that the graphics card is the problem? (I just don't want something more serious to be the cause.) Is it rare for a graphics card to just give up one day without much warning? It's worth noting that the computer and graphics card are both rather old (mid/late 2009) and that I'm not very smart when it comes to this type of stuff. I hope this is in the right forum and wasn't answered before. Thanks for any help!
