So where do I start....

2 weeks ago, my 3 months old HDD got corrupted(probably because I moved it around too much after we had moved to another house). Anyway, I issued a RMA and got my new HDD a week later, and immedeathly I encountered a problem when my mobo wouldn't recognize the HDD, as it displayed 'Disabled' where the name of the HDD should be in the UEFI menu. So what I did was just plug the SATA data cable into a different SATA port, and then it worked flawlessly! Installation went smooth, PC was fast and I didn't have any problems...

Until I installed Battlefield 4. Now my rig isn't the best in the world, but it definitely has the specs(see below) to run the game at 60 fps on Ultra. Anyway, the game would indeed run very smoothly at first, but after about 10 minutes it would suddenly crash, and no matter how many times I tried, it always crashed. Heck, eventually it would crash after 30 seconds! Also, the error Battlelog kept giving me was something along the trends of suddenly losing connection with the servers, but my internet didn't have any hickups.

Also, it couldn't be my PC as by comparison, other games like CS:GO and The Witcher 2 ran very smoothly without any problems at all.

However, this was the moment when everything got really bad. Around 2 days later, I noticed my PC got significantly slower, and would stutter very frequently, until just crashing altogether. It also gave me a blue screen:'Kernel_paging_error'. I found out my PC wouldn't yet again boot from my HDD, as my mobo kept displaying 'Disabled'.

That was a week ago, and I was really sure it was the HDD. But yet again, when I turned on my PC today. It did boot normally, albeit a bit slow still. After about 10 minutes of use it gave me another blue screen, 'critical_process failed' or something like that. I was literally on the verge of just taking my PC to the an electronics specialist, but I decided to turn it on one more time....And now it was really fast! Like as fast when I instanly put my replacement HDD in(after switching the SATA cables). Everything went smooth, and I checked my HDD and CPU with testing programs, and to my surprise the diagnostics didn't show anything wrong with them. Even when I installed to Windows 10 shortly after(which was an upgrade from 8.1 PRO) everything still was fast and smooth. However, while Battlefield 4 still crashed after around 10 minutes, everything else still worked smoothly(I tried CS:GO and LA Noire and those worked just fine). Also I found out when installing LA Noire, that my PC didn't have a recent version of DirectX(11 in this case).



Sorry for the long story, but as you might agree this whole thing has been very weird. That is why I hoped that somebody else could maybe tell me what the problem is, and maybe also why Battlefield 4 is that one game that keeps crashing for no reason.

Yes, that is what I instantly thought too. But wouldn't it be weird that suddenly now my PC is working normal again? And if the PSU was indeed killing off parts, wouldn't the diagnostics have shown that?
