What version of Precision?..Windows 10, huh?
 
Uninstalling Precision, restarting your PC and deleting the Precision leftovers located in the Program Files (x86) folder and installing Precision again has been known to fix the extra PrecisionX Server processes that start or remain running..Or using another version of Precision.

You can search the Forums for "PrecisionXServer Processes" and "PrecisionX Server Processes" and get some hits..Somebody 'said' they had 8,000 server processes running once, if you can believe that! 

Thanks for the replies, will keep an eye on this. 

Interesting you mention the spinning loading circle as I battled that in previous installs. In my current installation of Win 10 1803 I noticed that the most prior to latest PrecisionX release was responsible for a an intermittent loading wheel, it was noticeable as soon as I opened the program so it seemed likely directly related. However I no longer seem to be experiencing that with the latest PXOC release. I also don't appear to be having all of these multiple processes anymore. I would suggest installing the very latest PXOC again if you've gone a version back...
 
Regarding the spinning wheel, how often is it popping up? FYI if you use Chrome it's now normal procedure for the spinning wheel to appear for all sorts of stuff loading in Chrome like new tabs, web pages loading etc. This bugged me a lot, I thought there was something else going on and spent a lot of time trying to catch it, but then other people confirmed the same frequent loading wheel in Chrome. On the other hand I did actually also have another unrelated to Chrome intermittent spinning wheel. Clean installing Win 10 1803 seemed to have eliminated it. Those spinning circles can be very tough to pin point but if you notice a pattern I may have some ideas. Also I ended up changing my mouse pointer scheme to the Windows Standard (Large) hourglass, it's way less irritating than the blue spinning circle. Be sure after selecting Windows Standard (Large) to then click "use default" as it returns it to smaller more normal size.

Just thought of something. The spinning circle isn't continuous. It spins for a bit and then stops. A few seconds (minutes) later, it starts and stops again. I'm wondering if the circle is appearing when another entry for XOC server is being added to the task manager?? This may hard to catch as the next entry may not be added to the bottom of the list. But the next time I see the circle, I'll try to check this.

Everything was going great until at 7pm today, I saw the spinning circle next to the pointer and immediately checked task manager. Low and behold, multiple entries of PrecisionX server were appearing. So even with Revo Pro uninstall and clean reinstall it only lasted a little over 48hrs before it started again. I hope a moderator is checking and has an answer.

I read the PrecisionX server is only active when you have the OSD active. I may be using the program wrong, but I have it load minimized on start up. If I want to game, I open it up and click on OSD and HWM (to see how it looked afterwards). I think if you leave PXOC running minimized with the OSD checked, this is when you get the multiple entries appearing. I haven't seen the multiple entries occur today when the OSD was unchecked and the program still running minimized. ????

My last post on this for a while. I removed PrecisionX and installed Afterburner. Everything works. No glitches with this or some other minor problems I was having with Precision. I may check back but right now I see no problems using Afterburner. Too bad, I've been a user since 2006 but too many problems lately.
