HDD or RAM problem?

[Ozone9012]

So I recently tried to play the new Dying Light game on my PC. I launched it and just as I started playing I noticed I had some TERRIBLE lag. When I was staying still everything was OK, probably around 25-30 FPS, but as soon I as moved the mouse there was like a 5 sec lag. I also noticed that when I did not touch the PC the HDD usage was at 0% and then it suddenly jump at 100%.
Also, I added 2GB of RAM near my 4GB stick and I basically get BSoD when I play games. There is an increase in performance but not for long, because after playing a little it just gets Blue Screen. I don't know what the problem is. The OS detects 6GB of RAM in 2 sticks. The performance increase is there, but why BSoD??

What is the bsod stop error? Also go into admin tools, eventent viewer, windows logs, system. Look for disk or ntfs error. That would indicate a failing hard drive. Good luck!

What did you find out?

So it turns out i can't have 4GB on one stick and 2GB on the other. They are the same but there is some difference one is ECC and the other is Non-ECC. and one has small form and the other is normal
and the HDD is also almost broke

Thanks for the help anyway 😀
