Hi everyone so I would like to start this off by saying that I do not know very much at all about computers, really nothing at all infact, when installing things i just follow manuals. Anyways so about 3 years ago I got the following computer: CPU: AMD FX 6300 GPU: AMD Radeon 7730 Mobo: a960D+ So, eventually I upgraded my Graphics card to an Nvidia Gtx 950 FTW right but everything else stayed the same. Now, about 8 months after that upgrade, I have upgraded the processor while also switching over to intel. I switched to an I5 6600k and with it my new motherboard is a GA B150M D3SH. Right so now I have A 500 Watt PSU, a Gtx 950 FTW, an I5 6600k and my mobo is the GA B150M D3SH and for some reason in every game I am getting these stutters and lag spikes and it freezes for like 5-10 seconds. Well those are all compatible and I have the RAM too along with proper heating because I have looked at the temps and theyre all right where they should be, CPU averages 30-35 when not idle and GPU 60-70. Right so its not cooling, its not a compatibility problem either. Ive seen that it is one of the two following things: Option A: something is wrong and my hard drive is dying or whatever but I dont think that is it as this problem only now occurs with the new processor (So it started like 4 days ago.) The second possibility is that since I did not do a reinstall of my OS something is screwing up one of my new drivers, is that possible? I did not do a reinstall of my OS because I had no idea how to and there is not exactly any guides online that I was able to use (still dont know how). So if that is it and somebody can help with this, I would really appreciate that.
