How much memory have you got?
Is it all healthy?
Windows 8, 32 bits, 3GB of memory. But, what I don't understand, is that it's now impossible to export 1 picture, and before, I can export such as 30 pictures at the same time.
This error always happens when you don't have at least 8 GB or memory and a 64 bit operating system. The real fix is to have the proper hardware.
Try rebooting your computer and launching only Lightroom. If necessary, disconnect from the Internet, shut down your firewall and virus checker, and try again.

Maybe the RAM is failing.
I've tested the ram, everything seems ok. Today, I can export my pictures but something is strange. When i create my "print" file, I don't check my signature option. A few days ago, because I need the signature, I check it, and this was on my definitive picture, and now, without de-checking anything, the signature has disapeared. Bizarre !
