After replacing almost every part, pc still has major graphics issues

[Philosophy6]

After dealing with graphics issues ever since I got my new computer, almost 2 years ago, it got to the point where excessive BSODs were preventing me from using my graphics card at all, and after replacing my memory, which did nothing, then my card through RMA, I thought my problem had been fixed; so I went ahead and bought a second card for SLI. Sadly I was only able to enjoy using SLI for a short while, I don't remember how long, before the Blue Screens started coming again, preventing me from using my second card.

A week ago I replaced my PSU, which gave me a blue screen the second I clicked 'apply' to enable SLI. Yesterday I installed a new motherboard and CPU (I figured I should upgrade anyway) and I was greeted with 'windows failed to start' after installing my graphics drivers. Finally I decided my hdd had to be the culprit, so I replaced it with an oldish hdd in my basement. When I went to click 'apply' this time, nvidia control panel became completely unresponsive and froze my entire system. After restarting I got a very familiar BSOD, which looked like the same kind I got when I still had my first card.

BCCode: 116
BCP1: FFFFFA8008022010
BCP2: FFFFF880049882B0
BCP3: 0000000000000000
BCP4: 0000000000000002

Now both cards appear with Code 43 in device manager, and I have to disable both of them in order to start windows normally. This is after I have replaced my RAM, GPU, PSU, mobo, CPU and HDD. I've essentially bought a whole new computer but still have the bugs from the old one. What else can I possibly do?

only common factor in both builds seem to be your gtx 570 cards. Maybe one of them is failing.

Yes, but the cards from my current build are separate from the card from the old build. Neither one seems to have an individual problem on its own, and I doubt I would get three faulty cards in a row. The only thing I haven't truly replaced is my cd drive.

well try eliminating that (just unplug it) and see if the problem still persists. I doubt the cd drive is the problem though.

Nope, same Blue Screen.

Do you think it would do any good to bring it in for a professional to look at? I know it might not be the best idea but I don't really have any other options now.

I really think its your gpu(s).
