running Windows 7
16 gb ram
64 bit op system
3.30 ghz processer
My set up options at reboot DO NOT have an option to disable shadow caching in the BIOS section.....
I have moved several folders worth of images to my online storage to clear up space on the drives... ( we have a main as well as an external..)
I have run scan disk, defrag... I have run security checks with our antivirus program... I did not install any new hardware... the only thing new installed was the LR6...
This issue is seriously hindering my work flow. Any help would be appreciated tremendously!!!
Please and thank you!!!
And I figured out the corrupt catalog.. I had created a new one and didnt save/close it correctly.
System crashes are almost always caused by a hardware malfunction or bad/corrupted video driver. One thing that often causes this is a malfunctioning fan, causing your computer to overheat, but of course there could be other causes.
ended up being a harddrive going bad and a windows line error somewhere... scratched the whole thing and upgraded all my hardware and went to win 10...
