bsod on two of my pcs

[turop30]

Hello everyone this is my first time posting. But anyway I got two pcs that was just recently upgraded. One was a a8 5600k. 8gb corsair vengeance ram 1600. And r7770. And this pc was doing great for a long time. But I had a extra fx 6300 hundred and I wanted to move my a8 5600k to my othe dual core pc that was fm2 amd Athlon x2 340k. So about a week ago a changed everything around. I got a mobo of ebay that was supposed to be close to new which it looked it. But when got it. It didn't have bios to run fx cpus. So I flashed the bios and updateed um and it powerd up and ran fine. As did the old dual core pc that I put the a8 5600k in. It has a good gigabyte board that didnt need updat bios. It also had 4gb ripjaw 1600mhz ram and 6670 1gb. And it was the first to bsod after bout a week when i was playing a game. Now just hours ago my fx 6300 pc did the same as I was playing and game. And I have know idea about bsods just not hardware more then software some looking for any ideas. Also both pcs have avast thats only comin they have beside amd catalyst controls. And there all updated. So as I said im at a lost. And evetime I try to look at minidumb on either it says access denied. Even tho iwent in and made shure I had access. So any help would be appreciated. Thanks ahead.

If you switch around stuff like your CPU, REINSTALL WINDOWS. Drivers will stuff up, and all your stuff will start breaking. So backup, reinstall, restore. Easy peasy lemon squeezy. If this isn't to your liking, swap the parts back.

Since then I have reinstalled windows. And now im getting a random restart when gaming somtimes itll happen somtimes it wont. It restarts my pc and starts back up with no error or bsod it just did it tonight. So im at square one with not knowing what to do. I checked bios temps after shutdown and everything looked good cpu was only 36 degree. And mobo was 25 degree and gpu was 38. So I dont know whats up. Any help will be appreciated thank you.
