I've been trying to figure out why my PC typing was lagged and SSD active time is pegged at 100% during the first 20-30 seconds after logging into Windows. After disabling the start-up task and looking around I found this post.
 
It's definitely EVGA Precision X and has been happening for the last few months. Good thing it's not vital. I'm leaving it disabled until it's fixed. I also use profiles and have it start-up at log in.

It's definitely EVGA Precision X. I just switched to Afterburner and there is no type lag at startup. FIX IT!
 
edit: Windows 8.1 and SSD

I'm having this issue too. HUGE typing delay when I start up my computer and 99% disk usage. My girlfriend booted it up and even said "isnt this thing supposed to be really fast?" LOL with a GTX970 and fairly modern i5 I would want people to think this is at least better than my family's pentium 4. But this slow startup brings my computer to its knees.
 
I do have an SSD for my main windows drive (I saw people seem to have that in common with this issue). I also load overclock profiles.

I attempted to reproduce this on our test bench, but I was unable to with:
 
Windows 7 on an SSD
PrecisionX 5.2.3
X79 Dark
GTX 760 with ou without an overclock profile
 
I tried having it start with Windows both minimized and not, with and without a profile loaded, and I had no delays at all with startup in any way (launching program, typing, hangs while something loaded, etc.).
 
I would suggest uninstalling PrecisionX, then navigating to Program Files(x86)>EVGA and deleting the PrecisionX file, then reinstalling PrecisionX and see if that helps at all. There may be an old file that's gumming things up. Don't forget to write down any setting you put in PrecisionX, as you will lose them doing this.

Try another test bed with Windows 8.1? People complaining are on 8.1 if you might have missed that. You guys should have 2 different test benches any ways. One for 7 and one for 8.1

I'll do that when I get a chance. The Win 7 rig is just the one that was on and running when I went to do the testing, we do have a Win 8.1 system I can test further with. I'm off for my weekend, but I'll test it on Sunday when I come in.

Thanks Jason, I'm also on windows 8.1 if that helps. I'll try uninstalling and re-installing (and deleting that file)

same issue here, clean install of win 8.1
no matter what i try it just wont load at startup despite being checked to do so on the UI. No previous version files as its the latest version on a clean build. Any ideas?

Experience this as well- Windows 8.1, 64-bit, GTX 980 TI (but occurred on 680 as well when I had that). When PrecisionX is starting up, there is "typing lag" and general slowdown until the program loads. 

I am having this issue as well - have a very fast computer, GTX 980ti, Samsung SSD.  Could be related to Logitech keyboards that load Precision in the little LCD screen in the keyboard?  I have a Logitech G19 keyboard that loads precision monitoring stats in the keyboard LCD at startup.  Once this pops up, the typing lag goes away.  Takes about 30 seconds though which is ridiculous on this fast a computer.
