Photoshop CC 2014 - The file can not be saved in path because an error has occurred

Question

Hello,
I need again help regarding this issue. Sometimes but very often I receive an error, trying to save a PSD file, the error is: "The file can not be saved in <path> because an error has occurred". After that it is not possible to save the file in any format, using save or save in dialog. The only way to rescue the result is, to save for web as an jpeg. This error occours often using Topaz or NIK filter and until now only in PS-CC 2014. My workflow looks like this:
- Open NEF RAW file in Brdige
- Settings in ACR and give it into PS by clicking OK in ACR
- In PS doing a adjust some levels
- press SHIFT+STRG+ALT+E for a new summary layer
- Uing Topaz Adjust on the new level with 65% opacity
- press SHIFT+STRG+ALT+E for a new summary layer
- Using Topaz DeNoise on the new layer
- pres STRG+i and resize the image to 1200x797
- Using Topaz InFocus on the same layer as DeNoise
- create a vignette with brightness adjustlayer
After this workflow in nearly 90% it is not possible to save the file as PSD or something else, only to save for web as JPG. If I save the file after opening the RAW in PS and after every layer with Topaz Filter, I can save the file when I am done. Same issue occurs using NIK Filters in that way.
I tried to optimize the performance by using this guide: http://helpx.adobe.com/photoshop/kb/optimize-performance-photoshop-cs4-cs5.html doesn’t solve the issue.
I re- and installed all Adobe Products more than three times, doesn't solve the issu.
After that I ordered a new SSD drive and insall Windows 7 64bit inkl. All latest hotfixes, patches and drivers. I downloaded the newest Adobe Versions and the newest filter sets from Topaz and NIK. Doesn’t solve the issue.
This is my rig:
Gigabyte Z87X-UD4H mainboard
Intel Core i7 4770k
32GB Corsair RAM
250GB Samsung 840 Evo SSD Drive
nVidia Geforce GTX770
During my tests I took the same RAW File and created nearly 20 adjustment layers and summary layers, without using Topaz or NIK filters. No problem, I was able to save the file as PSD file. 
From my point of view, actually, the error occurs only when I am using Topaz or NIK filters. Both supports doesn’t know the issue and if I search the web, I can’t find more then me. It seemed to depend on my settings, my rig or something else, perhaps a cache is overflowed or something like this. Adobe telephone support can’t help because I said I use a third party filter. But it occurs with two different manufactures…
So please guys, help me to figure out why this error occurs in my system.
Thanks in Advance and best regards,

Update: I tried several times to reproduce the error, actually it dosen't occur. I changed nothing on my system, without reboot it twice. This is what I said in my beginning times: it occurs sometimes but often. I will keep you up to date.
