Windows 10 Lag after hardware change

Morning all

Im very stumped at the moment.

Recently changed my pc setup and now experiencing mouse lag, video playback lag and general slowness in windows 10, but not app opening times or boot times.
I swapped my 2x980 GPU for 2x1080Ti and changed my 6700 to a 6700k and a new corsair water cooler all stock clock speeds.

I have three SSD's in the machine 1xNVME 950 pro which i use for office work, 1x 950 ssd sata for gaming and a 940 ssd sata for an audio workstation build, all latest firmware.

All three disks are the identical base image of windows 10 just different software installed on each, i.e office drive has office 365 etc etc and game drive has uplay, steam etc.

Im only experiencing the slow down on the office drive the other two are fine.

All temps are fine, all drivers are up to date and identical on every build on each drive.

Spec is

gigabyte G1 gaming 7 - latest f21 bios
Intel core i7 6700k
Corsair vengeance 32GB DDR4
2x 1080Ti reference cards Sli
1x NVME M2 950 Pro 512GB
1x 950 SSD 512GB
1x 940 SSD 512GB

I've checked for malware, viruses, changed power management, removed and re-installed drivers and its still the same.
Resource monitor shows nothing of any significance and idling at 2% cpu usage
Event viewer shows nothing untoward.
Monitor is running at the correct 3840x2160@60Hz

The only step left is to re-image but that will take a while considering my outlook data file size.

anyone have any things I may have missed?

You could check the thermals of the drive. If it turns out to be the issue there are solutions: https://www.pugetsystems.com/labs/a...-2-Additional-Cooling-Testing-795/#Conclusion such as using a PCI-E adapter and a heatsink. Although you do have a pair of pretty hot GPUs stuffed in there.

When you say you removed and reinstalled the GPU drivers, did you use DDU to remove them? http://www.guru3d.com/files-details/display-driver-uninstaller-download.html If not, perhaps try that.

If you run the PC in safe mode, do you still get the same issue with mouse lag?

You could also try removing the 2nd GTX 1080 ti and seeing if that has any effect, then swapping it out with the 1st one.

Yeah I think the article I linked to speaks about thermals.

I know, I was agreeing with you - though in a way that is also a bit concerned if it is thermal throttling under basically next to no load.

Hi Guys

Thanks for the feedback, the odd thing is I haven't changed the M2 NVME drive that's always been in there and it doesn't do it on any of the other multi-boot operating systems so I don't think its GPU related or heat related, idle system temps in case are around 26-28 degrees C.

Safe mode is fine and no lagging occurs.

I didn't use a driver uninstaller when I changed GPU's but I will give it a go now, but its odd that it didn't affect the other two identical operating systems on different drives.

It feels like a background process is running that's consuming all the cpu resources but the system monitor would suggest different. (screenshot attached)
What I have noticed is that at the windows BCD selection screen the mouse is also very jumpy when choosing operating systems.

I will try removing one of the GPU's as well and report back.

Solved

Oussebon: You genius, the driver cleaner/remover worked so thanks for the tip.
I guess when you think about it the 980 and 1080 cards are different architecture so different drivers.

Thanks for everyone's input.

Cool, glad it seems to have worked :) Thanks for letting us know. Very jealous of your 1080 tis btw!

Unfortunately it was short lived, rebooted just now and its come back, jittery and jerky again :-(

The 1080s are great in Sli, constant 60fps+ in wildlands in 4k Ultra settings, shame im rubbish at games.

A new graphics update has just popped up from Nvidia so will give that a go next, if that doesn't fix it, time for a reload I think.

Ok so I feel a bit of a idiot now,found the problem purely by accident and why it wasn't do it when booting from the NVME game drive.

Went to use my bluray drive and saw it wasn't detected at all, looked in the chassis and saw half the SATA cable not plugged in to the Bluray drive properly, pulled it out completely and stuttering magically stopped guess half in it was causing the rest of the sata bus to play up hence why the PCI-E NVME didn't show the issue.

what a div I am.

again thanks for eveyones help.

Eh? In your original post you said the "office" drive which you said was the M2.

So why would a SATA connection issue be the problem?

Sure you're booting to the disks you think you are?

Oh well. Glad it's sorted.

I did think the DDU fix was a bit optimistic when suggesting it, it just seemed like the first catch-all thing to try since the biggest change to your system seemed to be the new GPUs. I wonder whether the process of fitting the new GPUs or whatever you did when fitting the new CPU wiggled the cable a bit loose(r). I'm not sure how exactly that would cause the issues you described but glad to hear it seems to be fixed this time. Touch wood. :)

Rep for reporting back anyway.

Tony, I mistyped the way round the disks are allocated, keep all games on the NVME for quick loading times.
I guess when I tried the DDU and powered off and back on I must have knocked the case under my desk just enough that it wasn't causing the connector to be disengaged.

When I changed all the hardware I re routed all the cables properly so it looked neat, I must had done it then.
again thanks for all the feedback and the rep.
