Trying to save file, but get one of two errors 50% of the time

Question

Here's a breakdown of my issue.
I'm a 3d artist working on some texture files for my models. I'm constantly saving the file to make quick changes and fixes, doing so quite rapidly. So much so I now have actions recorded to cut down on having to go to the directory to save over the older file. Now for the issue. I'll try saving over the file, but then I'll either be giving an error message saying "Could not save a copy as ________ because the file name was not valid" or "Could not save a copy as _________ because the file is locked, you do not have necessary access permissions, or another program is using the file. Use the Properties command in the Windows Explorer to unlock the file".
This is my personal pc so I do have the permissions enabled. If I open up the directory where the file is saved after I get these errors the file is then gone. These errors go away if I wait about 6 seconds in between getting the error to save then it has a better chance of working. That's not all of the time though. Sometimes I have to go in and just save manually, which is a real pain when I have actions recorded. It's almost like the relay between Photoshop and my directory isn't fast enough or something's just internally wrong. I've been dealing with this for a year. 11 months and 29 days too long. Help please!!!

BOILERPLATE TEXT:
Note that this is boilerplate text.
If you give complete and detailed information about your setup and the issue at hand,
such as your platform (Mac or Win),
exact versions of your OS, of Photoshop (not just "CS6", but something like CS6v.13.0.6) and of Bridge,
your settings in Photoshop > Preference > Performance
the type of file you were working on,
machine specs, such as total installed RAM, scratch file HDs, total available HD space, video card specs, including total VRAM installed,
what troubleshooting steps you have taken so far,
what error message(s) you receive,
if having issues opening raw files also the exact camera make and model that generated them,
if you're having printing issues, indicate the exact make and model of your printer, paper size, image dimensions in pixels (so many pixels wide by so many pixels high). if going through a RIP, specify that too.
A screen shot of your settings or of the image could be very helpful too,
etc.,
someone may be able to help you (not necessarily this poster, who is not a Windows user).
