Me/we as well. A quick ghost of all the basic apps and download a recent back of the my docs and off they go.
Harder in a houshold situation granted but thats what the phill half of the family use if no one able to sort a issue out on one of da puters.
Seen to many people in tears when there only copies of pictures, work files disspaear for ever.
When HDD's go kaput which happens quite often for various reasons.
I know of cases where people were so desperate for files on the deceased Hdd's they were prepared to pay hundreds of pounds for them to be professionally read plate by plate (even then there is no gurantee sadly)
A major local goverment buliding had a power failure recently and it took out many pcs some departments due to no back up policy were very badly affected. This has happened to other organisations i know of.
The lesson is as 99 percent of the people learn and start doing although a little late is back up regularly at least the files which are yours and unique.
Keep them in several places and on various medias, its worth the time and hassle trust me.
but if you need to sort the problem out you need to find out what is affecting the pc. If you had a "pop up" appear it sounds like you have some form of malware on the computer.
Can you now get in to windows at all?
Also can you use the keys to move around the Icons?
heres one example

I know of many examples where companies dont use mice or other pointing devices to move round windows. In fact it can be a lot quicker to just use keys.
If you can do everything other than use the mouse you may be able to scan the pc for malware with various free programs.
I hope you get it sorted
