Windows 7: Power outage system memory loss unexplained

Windows 7 Pro. 64/SP-1

Like we have all posted.
How you lost 6 days of data is somewhat a mystery.

Here are some definitions That might be helpful to understand things.

Volatile memory - Wikipedia, the free encyclopedia

Volatile memory or volatile storage, contrary to non-volatile memory, is computer memory that requires power to maintain the stored information; it retains its contents while powered, but when power is interrupted stored data is immediately lost.

Non-volatile memory - Wikipedia, the free encyclopedia

Non-volatile memory, nonvolatile memory, NVM or non-volatile storage is computer memory that can get back stored information even when not powered. Examples of non-volatile memory include read-only memory, flash memory, ferroelectric RAM (F-RAM), most types of magnetic computer storage devices (e.g. hard disks, floppy disks, and magnetic tape), optical discs, and early computer storage methods such as paper tape and punched cards.

***LMiller7 suggestion of backup is a great idea.
***windude99 Disk Check is another great idea.

I would do the backup first just in case you have a hard drive problem.

Samsung also has some hard drive test.

The 6 day data loss has still got me puzzled.
Check the time and date on your system. Just another guess.

Please keep us informed of any new information.

As has been mentioned data backup is essential if the data is important & can't be replaced.

Another very important item is an Uninterruptable Power Supply, usually referred to as a UPS. If you are working on a very important file or spreadsheet & the mains power suddenly fails the UPS will immediately cut in & give you enough time to save your work & shut the computer down.

I know these are suggestions after the horse has bolted, but are very good insurance to prevent work losses.

Thanks guys, I've checked everything, and all seems fine, but now I've taken the precaution of backing up to the cloud as well.
