Yes, now I have just installed the GeForce driver and PhysX driver. So nVidia HD Audio, Experience and 3D Vision drivers are not installed.

First of all, I've read the other related posts, but none of them solves my problem. I've built the computer myself, and with a few upgrades now and then. Been running smoothly since 2013 or something. The other day, it suddenly started to lag for a few seconds in the start of a game. Sometimes it stops, and it seems like the game is running fine, but other times it re-occurs while I'm playing. This goes for all games. I'm running Windows on a ssd, and BF4 on that disc as well. Running steamgames from an older hdd, but all games are acting the same. This is what I've done: 1. Tried reinstalling most of the drivers (perhaps not every single of alle the MB controllers, old MB) 2. Tried 3 different Graphic cards, so pretty safe to say that isnt the problem. (Tried 970, 780 and 1070). 3. Tested all my Ram chips. Got 4 x 4 in the computer, and actually one of them was bad, so is just running 2 x 4 (8 gb) right now. 4. Re-installed (clean install) Windows 10 and installed all drivers from scratch. 5. Tried to watch both resource monitor and windows event log, but nothing I could identify as errors. It actually disappeared when I changed from 970 to 780. But came back again before I switched to 1070. QUESTION: Could this be a hard drive (OS on Samsung EVO) or PSU-related ? And how do I best check this ?
