CPU: i7 6700k GPU: 980ti SLI RAM: 16GB DDR4 @ 2400MHz Motherboard: MSI ATX Z170A GAMING M7 SSD: Samsung 850 EVO 500GB HDD: Western Digital Blue 1TB
So, I built my computer around black friday / cyber monday of last year. Now, of course, being the idiot I am, I forgot to enable SLI and because it was my first time building a computer, I didn't even know I had to enable it besides the actual hardware part. Well, a few months go by, and everything is fine, however a few days ago and I look into it. It turns out my monitors were plugged into separate GPU's, so I fixed that and plugged them both into one. I have started experiencing problems ever since I enabled it(just about, not sure if enabling SLI caused it which was about 5 days ago).
Now, onto the problem. My computer starts out just fine when I turn it on. The majority of times that it the lag begins is after I alt-tab out of a game. For example, if I alt-tab out of CS:GO to Google Chrome on my other monitor, extreme lag sometimes ensues. It's not consistent at all. A few days prior, I disabled NVIDIA Geforce Experience from running on startup. For some reason, when I enabled it again, the lag stopped when I alt-tabbed out of CS:GO, however it still happened with other programs. It also happens if I leave my computer on / am AFK for a few minutes. It also happens when I close / open a youtube video as well. Of course, it doesn't always happen when I do these things. Sometimes, I can alt-tab and no problems present themselves. When my computer does lag out, I restart it and it works fine again until the lag starts again. I didn't download any programs besides a few games off of Steam, updating a few things programs and drivers. I was planning on restoring to a previous backup, but the backup that I would've restored to was very recently replaced by a new one where after the problem started happening. Currently, I am typing this while lagging. I have the Resource Monitor open right now and CPU usage has stayed between 2-10% and the memory has been consistently at around 2.8GB-3GB. All I have open is Steam, Google Chrome, Skype, and the Task Manager. I have run a few scans for viruses with Malware Bytes, however I shouldn't have a virus because I haven't download anything from any suspicious sources, only big name sites like steam and driver updates. I don't remember all the updates I have done in the past few days, but I believe I've updated Skype, Steam, Geforce Experience, Java, and GPU Drivers(tried downloading via NVIDIA's website and through Geforce Experience). Additionally, I have been getting an error sometimes when I shut down my PC for a while now(happened even before I enabled SLI) which was something along the lines of a system error (0xc0000142). I did some research and found the fix to it was to run command prompt as administrator and type sfc /scannow. It may have fixed the problem as I haven't seen the error as of yet, however time will tell because I didn't get the error too often.
Before I end this post, I'd like to describe the lag. When ever I drag a window around(such as Google Chrome), the window stutters and lags considerably. The computer slows down completely. Whenever I try and play games with the lag, its almost as if my computer costed as much as a loaf of bread with the FPS I'm getting(looks like 10). Somthing odd that happens is that even with the extreme lag drops(which continue in-game), the steam FPS overlay continues to display FPS numbers like no lag is happening such as 300+ FPS even though it looks like a slideshow.
I feel like I've done a bunch of trouble shooting while trying to figure out how I can consistently recreate the lag, but there are multiple ways and it doesn't happen 100% of the time. I really don't know what to do, and whether or not I should disable SLI and go back to my old setup(each monitor to a separate GPU). The only problem with that I'd feel like I'm wasting my money by not using the GPU's in SLI. Please, can someone help me!?
P.S. Once I revert back disable SLI, the lag stops happening. Please help!
