You have a graphics hardware issue most likely. Install a new driver or turn off OpenGL in the prefs. The otehr possible cuase could be permissions issues on your corporate network, where the PS swap file is being locked by some service or other tool or simple things such as having a disk quota. talk to your IT.
Thanks I will try the drivers, and feedback
I don't have disk quota.
We've also had people show similar issues due to bugs in antivirus software and malware.
One case was solved by reinstalling the OS - so we're not sure what external utility/problem was causing it.
Requiring a reboot means that the problem is outside of Photoshop.
I tried the drivers reinstall and it didn't work.
I disabled the openGL, the same.
It seems coming from compatibility with windows 7, but not sure. Because the problem appears when the computer is turn on for a very long time a day and a half.
We use Symantec EndPoint Protection for antivirus, is that it ?
I don't know what to do... use Gimp instead ?
