Alright, some backstory:
This particular pc first began having issues with a BSOD that I traced to the hard drive. As I traced the issue, I had occassional issues with not getting post beep or display. I would just restart the machine and it would work. Luckily, with the help of the internet, I was able to retrieve the data that was on the hard drive that had in fact gone bad.
Once I had that out of the way, I went to test the previous system with a new hard drive but find that the no posting/display issue is now persistent. When I plug my HDMI into the onboard display I do get post/display. During my troubleshooting, one time I started the pc and there was a high pitched whistle, as I had the case open I checked all the fans, but none of them were the issue. Sounded like the whistle was from the video card. After some research I found that it most likely wasn't receiving the correct power. I ensured that the power cables were secure into the PSU and the video card now, and I don't get the whistle. Unfortunately I don't have another rig that can handle this video card, so I can't cross test that way.
So at this point, I have a few questions. Is there any other way to test this card to make sure it is fried? If it is fried are there places to have it repaired (AMD Radeon HD 6970 2GB DDR5), would it be worth it (as in last a few years)? Are the hard drive/video card issues somehow related, via PSU or motherboard in any way? Thanks in advance.
