Over the past few months I have been having this absolutely terrible stuttering problem that occurs when literally doing anything on my computer. Stuttering happens when browsing the web, watching YouTube videos, scrolling through my Facebook feed, playing games, literally everything. Before I get any further, let me list out my specs and why I'm extremely p/o'd about this happening:

Specs:
CPU: I7 4790 4th Gen Haswell @ 3.6ghz [Turbo Boost enabled]
RAM: 2x 8gbs 2133mhz Corsair Vengeance
GPU: R9 390x
Power Supply: Rosewill 850W
Motherboard: GIGABYTE G1 Gaming GA-Z97X-Gaming GT
Storage: 2x Seagate 7200RPM 2TB HDDs

To give a little bit more detail on the issue, what exactly I mean by stuttering is that games, or videos, or whatever I am doing, seems to either slow down, or completely stop, for only a second, if that. So If I am playing a game, I will be running around and the game will stop for a second, as if it's rendering something in, and then continue as normal. This happens frequently though and these stutters happen within anywhere from a few seconds to a few tens of seconds.

I recently made a post on this forum and someone told me to lower my CPU clock, my CPU might be dying; I did that which seemed to solve the problem at that moment, but upon further testing I found out that it wasn't fixed. So I went ahead and ordered a replacement CPU, of the same exact model CPU, it arrived and, of course, I put it in. This had absolutely no affect on the problem.

I should also mention that at this point I have literally replaced every single part in my computer over the past six months trying to remedy this issue except for my Main hard drive, which I purchased from Staples about 10-12 months ago when my old hard drive died. Yup, you read that right. Everything, my Motherboard, CPU, RAM, Power Supply, and I even sent out my GPU to ASUS thinking that it was defective, tests concluded it was perfectly functioning.

List of Things I have tried to solve this problem:
Reinstalled Graphics Drivers (For both integrated Graphics (Intel 4600) and my main GPU).
Replaced numerous internal components
Reinstalled Windows
Reformatted my main hard drive
Installed Driver Booster 4 and updated all drivers found to be out of date.
Disabled CPU's Turbo boost and underclocked the CPU

If anyone has any possible solutions to this problem, even if it might be a long shot, please reply. I would greatly appreciate any tips or help anyone can give. Thank you.
 


1. CPU Pins can't be bent. I've tried two cpus on two different motherboards. And, Physically, everything looks perfectly fine.

2. I'll try that tonight.
