I have a computer with a 5970 2gb black edition. Originally, I was experiencing issues with artifacting, so I sent it in for a replacement. When i got the replacement, it worked for a day, and I left it on overnight, and when I looked at my computer the next day there was no signal. The monitor cables are fine, I had replaced the graphics card to PSU cables, everything was plugged in properly. So I took it to my friends house and he plugged it in and it worked fine on his computer. I figured it was the motherboard, so I replaced the motherboard. After just installing the motherboard, I still have no signal. I'm sure the monitors are working as I've tested them with my laptop. All RAM is seated properly, everything is in place, etc.
Before the artifacting/trouble ocurred, the GPU had been working steadily for years. It's kind of an old computer, DDR2 800 RAM, the motherboard I got is an MSI P43T-C51, etc.
Could it possibly be the power supply? It is around a year old, and well over the necessary limit for what I need (a 1000W PSU) or could it be the CPU or something?
Help is appreciated, thanks.
